SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0221 AM CST Wed Feb 12 2025 Valid 141200Z - 151200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are possible from the Sabine Valley into the Ozarks and Mid-South. Additional isolated storms are possible in the Four Corners vicinity. Severe weather is not currently expected. ...Synopsis... Shortwave ridging aloft will give way to strengthening southwesterly flow as a strong trough moves through the Southwest on Friday. Late in the period, moisture return will begin within the Sabine and lower Mississippi Valleys. A surface low will evolve southward from the central High Plains to the Red River region by Saturday morning. Warm advection will intensify as the trough nears the southern High Plains. Scattered to numerous storms are expected from the ArkLaTex into Mid-South/lower Ohio Valley Friday night into Saturday morning. Storms are possible farther south into East Texas and Louisiana, but warm air aloft leads to less certainty in development. Increasing shear and elevated instability will potentially promote a few stronger storms. However, modest mid-level lapse rates and plentiful storm interactions are expected to limit the severe threat. Small hail may occur, but the coverage of marginally severe hail appears too uncertain for unconditional probabilities. ..Wendt.. 02/12/2025 Read more

MD 0084 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR TEXAS COASTAL PLAIN...WESTERN AND CENTRAL LOUISIANA
Mesoscale Discussion 0084 NWS Storm Prediction Center Norman OK 0208 AM CST Wed Feb 12 2025 Areas affected...Texas Coastal Plain...Western and Central Louisiana Concerning...Severe potential...Watch unlikely Valid 120808Z - 120915Z Probability of Watch Issuance...20 percent SUMMARY...A marginal severe threat, with strong wind gusts and hail, is expected to develop late tonight into early this morning across parts of the Texas Coastal Plain into parts of western and central Louisiana. DISCUSSION...A mid-level shortwave trough will approach the southern Plains late tonight. In response, moisture advection will continue across the Texas Coastal Plain. At the surface, a quasi-stationary front is analyzed from near Laredo northeastward to northwest of Victoria to near College Station. The stronger convection is located to the west of this boundary. The RAP has MUCAPE varying from around 500 J/kg in southeast Texas to near 1500 J/kg in south Texas. As low-level moisture advection continues overnight, instability will gradually increase. Most RAP forecast soundings to the west of the front have a low-level temperature inversion, with effective shear above the inversion in the 50 to 60 knot range. This could support a marginal severe threat with the stronger elevated cores, with hail possible. As convective coverage increases, surface-based storms may develop near the front. The stronger cells could have marginally severe gusts, in addition to hail. ..Broyles/Mosier.. 02/12/2025 ...Please see www.spc.noaa.gov for graphic product...

Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0152 AM CST Wed Feb 12 2025 Valid 121200Z - 131200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE TRANS-PECOS... ...Synopsis... Within the base of a large-scale trough shifting eastward from the Rockies into the Plains, a belt of strengthening deep-layer westerly flow will overspread the southern Rockies and adjacent High Plains this afternoon. ...Texas Trans-Pecos... Diurnal heating and downslope-aided warming/drying will favor modestly deep boundary-layer mixing into the strong flow aloft across portions of the Trans-Pecos during the afternoon. As a result, 15-20 percent RH will develop amid 20-25 mph sustained westerly surface winds (with higher gusts). Given at least modestly receptive fuels here, elevated to critical fire-weather conditions are expected. Dry/breezy conditions will extend farther east into portions of central TX; however, recent measurable rainfall atop already marginal fuels will limit fire-weather concerns. Over southern NM, strong westerly surface winds will also support elevated fire-weather conditions, though cooler surface temperatures will limit RH reductions. ..Weinman.. 02/12/2025 ...Please see www.spc.noaa.gov/fire for graphic product...
