SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0103 AM CDT Tue May 06 2025 Valid 061200Z - 071200Z ...NO CRITICAL AREAS... ...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. ..Moore.. 05/06/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0100 AM CDT Tue May 06 2025 Valid 061200Z - 071200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF SOUTHEAST TEXAS... ...SUMMARY... Severe thunderstorms are likely today across parts of the southern Plains into the Lower Mississippi Valley. Some storms will be capable of producing severe gusts, large to very large hail, and tornadoes. Strong tornadoes will be possible. Isolated strong to severe storms with hail and marginally severe gusts may also occur in the northern Mid-Atlantic. ...Southern Plains/Lower Mississippi Valley... At mid-levels, a low will move into the southern Rockies today, as an associated 60 to 70 knot jet streak translates northeastward across the southern Plains. Within the exit region of the jet, scattered thunderstorms are expected to be ongoing in west Texas at the start of the period, along the western edge of a moist airmass. The moist airmass will be located over much of the eastern half of Texas extending eastward into the lower Mississippi Valley. Scattered to numerous thunderstorms are expected to develop around midday from north-central Texas into southern Oklahoma, in association with warm advection. A severe threat is expected to develop with this convection, and should increase during the afternoon. In areas that heat up, supercells with large hail and severe gusts will be possible. Hailstones of greater than 2 inches in diameter may occur with the more intense supercell updrafts, mainly in northwest and central Texas where mid-level lapse rates are forecast to be steep. Further to the southeast, the airmass is likely to remain undisturbed through midday. A warm front will move slowly northward across central and southeast Texas. From this front southward, surface dewpoints will likely be from the upper 60s to mid 70s F. As surface temperatures warm during the day, strong instability is forecast to develop. The models are in reasonably good agreement that MLCAPE will peak between 3000 and 4000 J/kg during the afternoon. In addition, the mid-level jet will move into the southern Plains, creating strong deep-layer shear favorable for supercells. In response, a 40 to 50 knot low-level jet is forecast to develop across southeast Texas. Forecast soundings to the northwest of the Houston area increase 0-3 km storm-relative helicity into the 350 to 400 m2/s2 range. This shear environment will be favorable for supercells and tornadoes. A few strong tornadoes will be possible within parts of the airmass that heat up the most and remain undisturbed into the early afternoon. MCS development appears likely during the afternoon across east Texas. Rotating storms within the MCS will be capable of large hail and severe gusts. This threat should spread eastward into the lower Mississippi Valley during the late afternoon and early evening. ...Northern Mid-Atlantic... A mid-level low will move northeastward across the Ohio Valley today, as a front advances eastward through the central Appalachians into the Mid-Atlantic. An axis of low-level moisture will be located ahead of the front with surface dewpoints in the 50s F. As surface temperatures heat up during the day, weak instability is forecast to develop along and near this moist axis. Low-level convergence and large-scale ascent associated with the mid-level system will likely support isolated to scattered thunderstorm development. In addition to the weak instability, RAP forecast soundings have moderate deep-layer shear in the Mid-Atlantic with steep low-level lapse rates exceeding 8 C/km. This could support a marginal wind-damage threat during the afternoon, with the threat eventually transitioning eastward into the Hudson River Valley. ..Broyles/Moore.. 05/06/2025 Read more

A mid-level low will move northeastward across the Ohio Valley today, as a front advances eastward through the central Appalachians into the Mid-Atlantic. An axis of low-level moisture will be located ahead of the front with surface dewpoints in the 50s F. As surface temperatures heat up during the day, weak instability is forecast to develop along and near this moist axis. Low-level convergence and large-scale ascent associated with the mid-level system will likely support isolated to scattered thunderstorm development. In addition to the weak instability, RAP forecast soundings have moderate deep-layer shear in the Mid-Atlantic with steep low-level lapse rates exceeding 8 C/km. This could support a marginal wind-damage threat during the afternoon, with the threat eventually transitioning eastward into the Hudson River Valley. ..Broyles/Moore.. 05/06/2025 Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0100 AM CDT Tue May 06 2025 Valid 061200Z - 071200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF SOUTHEAST TEXAS... ...SUMMARY... Severe thunderstorms are likely today across parts of the southern Plains into the Lower Mississippi Valley. Some storms will be capable of producing severe gusts, large to very large hail, and tornadoes. Strong tornadoes will be possible. Isolated strong to severe storms with hail and marginally severe gusts may also occur in the northern Mid-Atlantic. ...Southern Plains/Lower Mississippi Valley... At mid-levels, a low will move into the southern Rockies today, as an associated 60 to 70 knot jet streak translates northeastward across the southern Plains. Within the exit region of the jet, scattered thunderstorms are expected to be ongoing in west Texas at the start of the period, along the western edge of a moist airmass. The moist airmass will be located over much of the eastern half of Texas extending eastward into the lower Mississippi Valley. Scattered to numerous thunderstorms are expected to develop around midday from north-central Texas into southern Oklahoma, in association with warm advection. A severe threat is expected to develop with this convection, and should increase during the afternoon. In areas that heat up, supercells with large hail and severe gusts will be possible. Hailstones of greater than 2 inches in diameter may occur with the more intense supercell updrafts, mainly in northwest and central Texas where mid-level lapse rates are forecast to be steep. Further to the southeast, the airmass is likely to remain undisturbed through midday. A warm front will move slowly northward across central and southeast Texas. From this front southward, surface dewpoints will likely be from the upper 60s to mid 70s F. As surface temperatures warm during the day, strong instability is forecast to develop. The models are in reasonably good agreement that MLCAPE will peak between 3000 and 4000 J/kg during the afternoon. In addition, the mid-level jet will move into the southern Plains, creating strong deep-layer shear favorable for supercells. In response, a 40 to 50 knot low-level jet is forecast to develop across southeast Texas. Forecast soundings to the northwest of the Houston area increase 0-3 km storm-relative helicity into the 350 to 400 m2/s2 range. This shear environment will be favorable for supercells and tornadoes. A few strong tornadoes will be possible within parts of the airmass that heat up the most and remain undisturbed into the early afternoon. MCS development appears likely during the afternoon across east Texas. Rotating storms within the MCS will be capable of large hail and severe gusts. This threat should spread eastward into the lower Mississippi Valley during the late afternoon and early evening. ...Northern Mid-Atlantic...

Some Lehigh Acres residents have been without water for weeks after their wells went dry. The Sandstone Aquifer has dropped to record lows in some areas. Outdoor watering was permitted once weekly in Lee County to protect the aquifer. WFTX-TV FOX 4 (Cape Coral, Fla.), May 5, 2025 Wells in Lehigh Acres were running dry as drought persisted in the region. Many homes do not have enough water to shower or prepare meals, and well and plumbing businesses were getting many calls for service. Gulf Coast News Now (Fla.), April 28, 2025
