SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0158 AM CDT Thu Aug 01 2024 Valid 021200Z - 031200Z ...Synopsis... Along the western periphery of an expansive midlevel anticyclone centered over the central Rockies/Intermountain West, a midlevel vorticity maximum will advance northward from southern CA into OR through the period. Preceding this feature, a plume of sufficient midlevel moisture, atop a diurnally deepening boundary layer, will support isolated to widely scattered high-based thunderstorms. Storms will develop over CA during the afternoon, and gradually spread/develop northward (in tandem with the vorticity maximum) across the Northwest into the overnight hours. Given dry fuels across many of these areas, isolated lightning-induced ignitions will be possible. Confidence in thunderstorm development is lower with northward extent into WA, though sufficient instability and glancing ascent ahead of a midlevel trough could still yield isolated storms. ..Weinman.. 08/01/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0157 AM CDT Thu Aug 01 2024 Valid 011200Z - 021200Z ...NO CRITICAL AREAS... ...Synopsis... An expansive mid/upper-level ridge will build across the western CONUS today. Along the southern periphery of the ridge, a midlevel vorticity maximum -- currently evident in water-vapor imagery near the northern Gulf of CA -- will continue west-northwestward across southern CA. Increasing midlevel moisture and ascent preceding this feature will support isolated thunderstorms across portions of southern CA into the overnight hours. While a mix of wet/dry thunderstorms could favor some threat of lightning-induced ignitions over dry fuels, the dry-thunderstorm risk appears too localized for highlights at this time. Along the western periphery of the ridge, moderate south-southwesterly midlevel flow will overspread northern CA into OR. Here, boundary-layer mixing into the enhanced flow aloft will contribute to locally dry/breezy conditions during the afternoon -- especially within terrain-favored areas such as the Shasta Valley. While locally elevated fire-weather conditions are possible, the threat is too localized for an Elevated area. ..Weinman.. 08/01/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 0600Z Day 2 Outlook
Day 2 Convective Outlook CORR 1 NWS Storm Prediction Center Norman OK 0141 AM CDT Thu Aug 01 2024 Valid 021200Z - 031200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM THE OHIO VALLEY TO THE SOUTHEAST AND MID-ATLANTIC... CORRECTED FOR GENERAL THUNDERSTORM LINE FACING THE WRONG DIRECTION ...SUMMARY... Scattered strong to occasionally severe storms are possible on Friday from the Ohio/Tennessee Valley to the Atlantic Coast. ...Synopsis... A upper low across northeast Illinois Friday morning will move slowly east through the day before stalling Friday night in the Upper Ohio Valley. A surface low in the southern Great Lakes region will weaken during the day with a diffuse cold front extending from central Ohio to the Mid-Mississippi Valley. ...Ohio Valley to the Mid-Atlantic and the Southeast... A very moist airmass will remain across the Ohio Valley/Tennessee Valley to the Atlantic Coast on Friday. Therefore, moderate to strong instability is expected across much of the region as temperatures warm into the 90s. Weak height falls, a weak/diffuse cold front, and lee troughing east of the Appalachians will all support widespread thunderstorm activity Friday afternoon/evening. Deep-layer shear will be relatively weak (15 to 20 knots), but the strongly unstable environment and hot/moist boundary layer will support the threat for some strong to severe storms with a primary threat of severe gusts. ...Southern Arizona... Monsoon moisture is forecast to surge northward into southern Arizona on Friday as temperatures warm over 100F. Southeasterly mid-level flow of 15-20 knots around the southern periphery of the mid-level ridge will aid in storm organization and may result a few strong to severe storms. The deeply mixed boundary layer will support a primary threat of severe gusts. If storms can congeal once they move off the higher terrain, higher probabilities may be warranted. ..Bentley.. 08/01/2024 Read more

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 587 NWS Storm Prediction Center Norman OK 935 PM CDT Wed Jul 31 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Eastern Kansas Western into Central and Northern Missouri * Effective this Wednesday night and Thursday morning from 935 PM until 300 AM CDT. * Primary threats include... Widespread damaging winds and isolated significant gusts to 80 mph likely Isolated large hail events to 1.5 inches in diameter possible SUMMARY...A severe squall line will move from west to east across the Watch area tonight. Severe gusts 60-80 mph are the primary hazard with the stronger outflow surges. The severe thunderstorm watch area is approximately along and 75 statute miles east and west of a line from 30 miles north northwest of Chillicothe MO to 55 miles southwest of Knob Noster MO.
