NWS headlines - Top News feature

• ...Severe Weather Possible In Northern Plains and Southeast...
  The NWS Storm Prediction Center is forecasting a Slight Risk of severe thunderstorms today across portions of the northern Plains, from North Dakota southward across northwest Nebraska and into western/north-central Minnesota as well as over parts of the Southeast, from eastern Alabama and parts of the Florida Panhandle northeastward across much of Georgia, South Carolina and into southwestern North Carolina. The main threats will be damaging wind and hail, though tornadoes are possible in the northern Plains Slight Risk area.
  
• ...Fire Potential Increasing in the West...
  Hot, dry and windy weather has allowed vegetation to dry in the West, and this has increased the fire danger. Over the next few days, fire weather concerns will markedly increase as gusty winds develop. Any wildfires that start will have the potential to quickly grow out of control. Red Flag Warnings cover a large portion of the Southwest through the Central Rockies.
  
• ...Fire Weather Watches In Effect for the Southwest...
  Over the next few days, fire weather concerns will increase as a trough moves through the desert southwest. Continued dry conditions combined with intensifying winds will up the likelihood of fast spreading fires, if one were to start. These conditions will also make controlling the on-going fires in this area more difficult.
  
• ...High Surf and Rip Current Threat Continues From Tropical Storm Alberto...
  Tropical Storm Alberto continues to swirl off the Georgia and South Carolina coast, but Tropical Storm conditions are no longer expected on shore, so the Tropical Storm Watch has been cancelled. High surf and dangerous rip currents will continue to be a hazard along the coasts of Georgia, South Carolina, and northeastern Florida.
  
• ...Alberto has Weakened Slightly, but a Tropical Storm Watch Remains in Effect for coastal South Carolina...
  Alberto is moving toward the west-southwest near 6 mph but is expected to slow down and meander off the coast of Georgia and South Carolina through Monday. A northeastward acceleration is anticipated Monday night and Tuesday. On this track, the center of Alberto is forecast to remain offshore. A Tropical Storm Watch remains in effect for portions of coastal South Carolina.
  
• ...Tropical Storm Alberto Still Moving Slowly off the South Carolina Coast...
  Tropical Storm Alberto is drifting toward the South Carolina coast this morning, but it is expected to gradually change direction toward the northeast later today. Tropical Storm force winds will be possible in parts of coastal South Carolina later today and Monday, so a Tropical Storm Watch has been issued.
  
• ...First Tropical Storm of the Atlantic Season Forms off the Coast of the Carolinas...
  Tropical Storm Alberto has formed off the coast of the Carolinas. Alberto is earliest-forming tropical storm in the Atlantic basin since Ana in 2003. This is also the first time that a tropical storm has formed before the official start of the hurricane season in both the Atlantic and East Pacific basins.
  
• ...Active Weather Will Continue to Develop Across the Central Plains and Upper Mississippi Valley...
  A low pressure system will enhance showers and thunderstorms from the central plains to the upper Mississippi river valley Saturday. A surface front ahead of the low will aid in the development of convective activity throughout the day into the evening hours. Meanwhile, high pressure will persist over New England, while a stationary low pressure system off the central Atlantic coast will maintain showers and thunderstorms along the southeastern coast.
  
• ...Active Weather Will Continue Across the Rockies and Upper Midwest This Weekend...
  Widespread showers and thunderstorms will accompany a surface front slowly moving over the central Rockies to the Upper Midwest this weekend. High pressure will hold strong over New England, while a low pressure system off the southern Atlantic coast will keep showers and thunderstorms in the forecast from Florida to the coastal Carolinas.
  
• ...Rain and Thunderstorms Continue to Develop Over Parts of the Southeast, North-Central and Western U.S...
  Scattered showers and thunderstorms will continue to develop into this evening for portions of the Carolinas, the Southeast, central Rockies and northern Great Plains. Isolated, marginally-severe, storms will be possible over these locations. Meanwhile, pleasant weather is expected for most of the eastern U.S. for the next few days.
  
• ...Rain and Thunderstorms Forecast for Parts of Southeast, North-Central and Western U.S...
  Scattered rain and thunderstorms are forecast today for parts of the Southeast, central Rockies and northern Great Plains, with isolated, marginally-severe, storms in the northern Plains. Meanwhile, pleasant weather is expected for most of the eastern U.S. for the next few days.
  
• ...Critical Fire Weather Threat Friday Over the Four-Corners Region of the Southwest...
  A combination of strong winds, low humidity, and ongoing dry weather will lead to another day of critical fire weather danger in the Four-Corners region of the southwest Friday. Red Flag Warnings remain in effect over a large area.
  
• ...Pleasant Weather Returns to East Coast, Showers and Thunderstorms Possible for Parts of Southeast, Midwest, Rockies...
  After several days of warm and moderately muggy conditions over much of the eastern U.S., a cold front moving in from the Great Lakes region will bring a welcomed return of cooler and less humid weather for the end of the week. Meanwhile, scattered rain and thunderstorms are forecast today for parts of the Southeast, central Rockies, and Midwest.
  
• ...Critical Fire Weather Threat for Thursday...
  The fire weather threat will reach the critical level in the southwest on Thursday. Elsewhere in the west, the fire weather threat will remain elevated as a system pushes through. Strong winds and thunderstorms capable of producing lightning but little precipitation will move through the region, increasing the chances for a fire to spark and spread quickly.
  
• ...Slight Risk for Severe Storms for Parts of Pa., N.Y., New England...
  The NWS Storm Prediction Center is forecasting a Slight Risk for severe thunderstorms for northeastern Pennsylvania central, eastern and upstate New York and western New England. The main threats will be damaging hail and wind. Meanwhile, sea breeze-driven storms will occur this afternoon over the eastern Carolinas. A few strong to severe storms will be capable of damaging winds.
  
• ...Thunderstorms Likely in New England on Wednesday...
  Severe thunderstorm activity will shift to the north on Wednesday, bringing the threat of wind and hail to New England. The Storm Prediction Center is forecasting storms for mid-day ahead of an advancing cold front.
  
• ...Severe Weather Possible for Parts of Great Lakes and Mid-Atlantic...
  The NWS Storm Prediction Center is forecasting a Slight Risk of severe thunderstorms for parts of the lower Great Lakes region and upper Mississippi Valley, as well as for parts of the Mid-Atlantic, including much of the Carolinas, Virginia and Maryland. The main threats will be large hail and damaging winds, although there is a minimal threat of brief tornadoes.
  
• ...Fire Weather Potential is Increasing in the Southwestern U.S...
  With daytime temperatures above 100 degrees and dew points in the single digits and teens, the potential for fire weather is increasing in the desert southwest. Wind speeds will increase across this region on Tuesday. Should a fire begin, it will rapidly spread due to the dry and windy conditions.
  
• ...Severe Thunderstorms Possible for Parts of West/Southwest Texas...
  The NWS Storm Prediction Center is forecasting a Slight Risk of severe thunderstorms through tonight for parts of west/southwest Texas and the Rio Grande Valley. Large hail, damaging winds and isolated tornadoes are possible. Meanwhile, a secondary area of strong to severe storms capable of damaging winds exists from the Mid-Atlantic to the Southeast U.S.
  
• ...It’s feeling Hot Hot Hot in the Desert Southwest...
  Excessive Heat Watches and Warnings are in effect for portions of southern California and Arizona. Temperatures in excess of 110 degrees are possible over the next few days. This will be the first stretch of excessive heat in this area for 2012.
  
• ...Significant Rains Early This Week From the Piedmont to Northern New England...
  A slow moving moisture laden storm system will spread an axis of moderate to heavy rain northward from the Piedmont and Mid-Atlantic into Interior New England early this week. Widespread rainfall of one to three inches is expected through early Wednesday with a chance for localized flooding, especially over portions of eastern Pennsylvania.
  
• ...Drought Conditions Improving for Portions of Texas...
  At the beginning of the year, nearly 55% of Texas was in severe drought or worse. Precipitation over the past four months has alleviated drought conditions across the southern and eastern portions of the state. As of May 8, 2012, only 25% of the state was experiencing severe drought or worse.
  
• ...Summer-like Heat in the Southwest...
  Temperatures Saturday morning are cool across the northern tier of the US and into New England, but summer-like heat is returning to the southwestern states today. An Excessive Heat Warning has been issued for the deserts of southeastern California and southwestern Arizona, where temperatures up to 105 degrees are possible Saturday afternoon. Highs in the mid to upper 90s will be common throughout California's Central Valley.
  
• ...Flash Flood Threat Shifts to Southeast Louisiana and Southern Mississippi for Saturday...
  A disturbance moving through the southern Great Plains will continue to provide a threat for severe weather and heavy rainfall across eastern Texas tonight. The threat for heavy rainfall will shift into southeast Louisiana and southern Mississippi for Saturday. Rainfall amounts of 2 to 4 inches, with locally heavier amounts are possible. Repeat areas of very heavy rainfall may result in flash flooding of streets, canals, small stream as well as low-lying and poor drainage areas. Remember: Turn Around Don't Drown
  
• ...Heavy Rain Expected for Gulf Coast...
  Heavy rainfall and flash floods are possible across southeast Texas and western Louisiana today. Several inches of rainfall are expected, which could lead to flooding of urban areas and small creeks. Meanwhile, isolated severe thunderstorms are possible across the central Gulf Coast, where the main threats will be large hail and damaging winds.
  
• ...Flash Flood Threat Shifts to Southeast Texas and Southern Louisiana for Remainder of Week...
  A disturbance moving into the southern Great Plains will continue to provide a threat for heavy rainfall capable of flash flooding across southern Texas tonight. As this system migrates east, expect the flash flood threat to shift into southeast Texas and southern Louisiana for Friday and Saturday. Amounts of 2-4 inches will be common across this region through the period, with locally heavier amounts possible. This system may also lead to river rises across the region for early next week. Remember: Turn Around Don't Drown
  
• ...Rain and Thunderstorms Possible Across Portions of Texas...
  Heavy rainfall and flash floods are possible today across central and southern Texas. Several inches of rainfall are expected, which could lead to flooding of urban areas and small creeks. Meanwhile, severe thunderstorms are possible across southern Texas, with large hail, damaging winds and weak tornadoes possible.
  
• ...Heavy Rain Capable of Flash Flooding Likely for Southern Texas...
  A slow moving disturbance in northwest Mexico will track across the southern Great Plains Thursday through Saturday. Although this system is weakening, it will encounter an air mass with abundant moisture, leading to the potential for heavy rainfall. Amounts ranging from 2 to 4 inches will be common across southern and southeast Texas from Thursday evening through Friday afternoon, with locally heavier amounts up to 6 inches possible. Locations that may be impacted by the heavy rainfall include Austin, San Antonio, Corpus Christi and Houston. Flash Flood Watches have been posted for portions of southern Texas. Remember: Turn Around Don't Drown
  
• ...Rain, Thunderstorms Possible along Eastern Seaboard and Gulf Coast into Desert Southwest...
  A cold front pushing towards the Eastern Seaboard will bring another day of unsettled weather from Florida to Maine on Wednesday, with severe weather possible from the Mid-Atlantic to the southeast. Meanwhile, rain and thunderstorms are possible along the Gulf Coast into the Desert Southwest, with conditions remaining favorable for widespread thunderstorm activity across much of Texas into Thursday.
  
• ...La Niña Transitioned to ENSO-Neutral Conditions...
  La Niña dissipated during the month of April as below average sub-surface temperatures largely disappeared and above average sub-surface temperatures expanded in both the central and eastern Pacific. The current and evolving conditions, combined with model forecasts, suggest La Niña is unlikely to redevelop later this year. The official forecast calls for ENSO-neutral conditions through the JAS (July-August-September) season, followed by approximately equal chances of neutral or El Niño conditions for the remainder of the year.
