SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1133 AM CDT Tue May 06 2025 Valid 061700Z - 071200Z ...NO CRITICAL AREAS... No changes are needed to the D1 Fire Weather Outlook. See previous discussion below for more information. ..Thornton.. 05/06/2025 .PREV DISCUSSION... /ISSUED 0103 AM CDT Tue May 06 2025/ ...Synopsis... Fire weather concerns are forecast to remain limited for today across the country, though localized concerns may emerge across parts of southwest TX. An upper low across the Southwest will continue eastward into the southern Plains through the day. As this occurs, a westerly downslope flow regime will become established across the southern Rockies with sustained winds generally in the teens. A dry air mass in place across northern Mexico and along the upper Rio Grande will spread east, resulting in afternoon minimum RH reductions in the low teens. Latest ensemble guidance continues to show some potential for elevated fire weather conditions from the upper Rio Grande into the Trans Pecos and Big Bend regions - especially on the leeward side of more prominent terrain features where downslope winds/drying will be enhanced. However, confidence in sustained/widespread elevated conditions remains too limited to warrant risk highlights. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1130 AM CDT Tue May 06 2025 Valid 061630Z - 071200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS CENTRAL AND EAST/SOUTHEAST TEXAS TO WESTERN LOUISIANA... ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE NORTHERN MID-ATLANTIC/NORTHEAST... ...SUMMARY... Severe thunderstorms are expected today into this evening, especially across parts of central into east/southeast Texas and Louisiana. Large to very large hail, damaging winds, and tornadoes, potentially a few of which may be strong, should occur. Severe thunderstorms may also develop this afternoon across parts of the northern Mid-Atlantic/Northeast and the Florida Peninsula. ...Southern Plains into the Lower Mississippi Valley... Multiple supercells are ongoing late this morning across central TX along/near a surface warm front. As an upper trough/low continues to eject eastward over the southern Plains today, a rather favorable environment will be in place this afternoon and evening for intense severe thunderstorms across central/east-central TX into LA. Even with continued cloudiness across the warm sector, filtered daytime heating and the presence of modestly steep mid-level lapse rates will support moderate to locally strong instability given the rich/moist low-level airmass present. Ample low-level and deep-layer shear will foster continued updraft organization, including the potential for several supercells. The greatest potential for tornadoes, some of which could be strong, will likely remain focused along/near the warm front, which will attempt to lift northward some across east TX and LA through the afternoon and evening. Otherwise, large hail will be possible north of the warm front with elevated supercells. A severe/damaging wind threat will exist with any clusters that can become established. The tornado and damaging wind threat will probably continue through the evening and perhaps overnight hours across parts of the lower MS Valley, given sufficient instability and strong low-level shear along/near the warm front. Have therefore adjusted the Slight Risk eastward some across this region. Have also trimmed the Slight Risk from the southern High Plains, as low-topped convection closer to the cold-core upper low will probably only have access to weak instability this afternoon/evening. Still, this activity may have an isolated hail/wind threat, and the Marginal Risk has been maintained across the southern High Plains for this potential. ...Northern Mid-Atlantic/Northeast... Even in the presence of some cloud cover, thunderstorm development and intensification will occur this afternoon across parts of the northern Mid-Atlantic and vicinity in a modestly moist/unstable air mass preceding an upper low over the upper OH Valley. Relatively steep lapse rates aloft and moderate to strong deep-layer south-southwesterly flow should support organized convection capable of severe hail and damaging winds. The best severe threat should remain focused across parts of eastern PA into NJ and southern NY, where the Slight Risk has been maintained with only small expansions. ...Florida... Upper ridging should be more influential today over FL compared to yesterday. Still, cool temperatures aloft and moderate instability could support occasionally strong to severe thunderstorms capable of producing isolated hail and/or damaging winds this afternoon across parts of the FL Peninsula along/south of a remnant front. ..Gleason/Squitieri.. 05/06/2025 Read more

SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1130 AM CDT Tue May 06 2025 Valid 061630Z - 071200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS CENTRAL AND EAST/SOUTHEAST TEXAS TO WESTERN LOUISIANA... ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE NORTHERN MID-ATLANTIC/NORTHEAST... ...SUMMARY... Severe thunderstorms are expected today into this evening, especially across parts of central into east/southeast Texas and Louisiana. Large to very large hail, damaging winds, and tornadoes, potentially a few of which may be strong, should occur. Severe thunderstorms may also develop this afternoon across parts of the northern Mid-Atlantic/Northeast and the Florida Peninsula. ...Southern Plains into the Lower Mississippi Valley... Multiple supercells are ongoing late this morning across central TX along/near a surface warm front. As an upper trough/low continues to eject eastward over the southern Plains today, a rather favorable environment will be in place this afternoon and evening for intense severe thunderstorms across central/east-central TX into LA. Even with continued cloudiness across the warm sector, filtered daytime heating and the presence of modestly steep mid-level lapse rates will support moderate to locally strong instability given the rich/moist low-level airmass present. Ample low-level and deep-layer shear will foster continued updraft organization, including the potential for several supercells. The greatest potential for tornadoes, some of which could be strong, will likely remain focused along/near the warm front, which will attempt to lift northward some across east TX and LA through the afternoon and evening. Otherwise, large hail will be possible north of the warm front with elevated supercells. A severe/damaging wind threat will exist with any clusters that can become established. The tornado and damaging wind threat will probably continue through the evening and perhaps overnight hours across parts of the lower MS Valley, given sufficient instability and strong low-level shear along/near the warm front. Have therefore adjusted the Slight Risk eastward some across this region. Have also trimmed the Slight Risk from the southern High Plains, as low-topped convection closer to the cold-core upper low will probably only have access to weak instability this afternoon/evening. Still, this activity may have an isolated hail/wind threat, and the Marginal Risk has been maintained across the southern High Plains for this potential. ...Northern Mid-Atlantic/Northeast... Even in the presence of some cloud cover, thunderstorm development and intensification will occur this afternoon across parts of the northern Mid-Atlantic and vicinity in a modestly moist/unstable air mass preceding an upper low over the upper OH Valley. Relatively steep lapse rates aloft and moderate to strong deep-layer south-southwesterly flow should support organized convection capable of severe hail and damaging winds. The best severe threat should remain focused across parts of eastern PA into NJ and southern NY, where the Slight Risk has been maintained with only small expansions. ...Florida... Upper ridging should be more influential today over FL compared to yesterday. Still, cool temperatures aloft and moderate instability could support occasionally strong to severe thunderstorms capable of producing isolated hail and/or damaging winds this afternoon across parts of the FL Peninsula along/south of a remnant front. ..Gleason/Squitieri.. 05/06/2025 Read more
