SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0228 AM CDT Wed Sep 24 2025 Valid 261200Z - 271200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Scattered thunderstorms are likely across the Southeast and into the Carolinas on Friday. A few stronger storms may be possible near the coast from Georgia to North Carolina. ...Synopsis... A cutoff low will develop in the Tennessee Valley region on Thursday night and drift slowly east on Friday. At the surface, high pressure will build into much of the eastern CONUS with a synoptic front stalled near the Georgia/South Carolina/North Carolina coast. Farther west, a mid-level cutoff low will develop somewhere near southern California/northern Baja during the day Friday. ...Southeast Coast... Weak to potentially moderate instability is forecast to develop ahead of a cold front near the Southeast Coast on Friday. Mid-level flow around 30 knots may provide enough deep-layer shear for a few strong storms. However, overall modest instability and shear within a narrow corridor along the Southeast coast precludes the need for severe weather probabilities at this time. ...Southwest.. Moderate instability and moderate lapse rates are forecast across southern Arizona on Friday as some monsoon moisture is pulled north ahead of the cutoff low to the west. In addition, some moderate 30 to 35 knot mid-level flow is forecast to overspread this region Friday afternoon/evening. This will provide an environment which may support a few strong storms capable of gusty winds. ..Bentley.. 09/24/2025 Read more

MD 2126 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTHWEST/SOUTH-CENTRAL AR
Mesoscale Discussion 2126 NWS Storm Prediction Center Norman OK 0224 AM CDT Wed Sep 24 2025 Areas affected...Southwest/south-central AR Concerning...Severe potential...Watch unlikely Valid 240724Z - 240830Z Probability of Watch Issuance...5 percent SUMMARY...An isolated large hail and strong gust threat is possible with sporadic intensification and weakening of individual storm cells across southern Arkansas through the pre-dawn hours. DISCUSSION...Embedded within a broader swath of mainly weak convective and stratiform elements, one cell briefly intensified across southwest AR. Before pulsing down again, it did contain a robust MRMS MESH signature, hail spike, and CC min indicative of a large hail core in the mid levels. Stratiform immediately ahead of this cell has diminished, which may support another round or two of reintensification of this cell or other nearby updrafts over the next 2-3 hours. Background environment is characterized by very high PW values of 2-2.25 inches per GPS PW data, amid weak, moist-adiabatic tropospheric lapse rates. In addition, RAP forecast soundings appear to be slightly too strong with 6-9 km AGL winds per area VWP data. As such, large hail cores should struggle to be sustained, with peak sizes likely remaining in the quarter to golf ball range. Locally strong gusts, amid otherwise background light surface winds, are possible in collapsing cores. ..Grams/Gleason.. 09/24/2025 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0146 AM CDT Wed Sep 24 2025 Valid 251200Z - 261200Z ...CRITICAL FIRE WEATHER AREA FOR NORTH CASCADES INTO THE COLUMBIA BASIN... ...Synopsis... As a mid-level jet moves onshore over Washington on Thursday, west-southwesterly winds aloft will result in dry and gusty downslope winds over eastern portions of the North Cascades and into the Columbia Basin. Critical fire-weather conditions are expected. ...North Cascades into the Columbia Basin... West-northwesterly surface winds of 20-25 MPH (locally gusting as high as 30-35 MPH) are forecast through the Cascade gaps and into the Columbia Basin, where relative humidity should dip to 10-15%. With forecast fuels guidance showing ERCs approaching or at the 90th annual percentile, Critical highlights have been introduced -- especially given the presence of ongoing fires in the region. Maximum winds are expected to peak beginning around 2 PM PDT Thursday, and diminish by 8 PM PDT. ...Sierra Nevada into the southern Great Basin... An upper-low is expected to bring thunderstorm activity to the Sierra Nevada, southern Great Basin, and Arizona regions. Higher precipitable water content and marginal fuel receptiveness will diminish fire-weather concerns. ..Halbert.. 09/24/2025 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
