SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1250 AM CST Sun Jan 25 2026 Valid 261200Z - 271200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms appear unlikely Monday. ...Synopsis... A strong upper trough initially centered across the Plains and Great Lakes will move off the East Coast by early Tuesday. A second upper trough over the Canadian Prairies will subsequently move southward and intensify over the northern US as ridging builds over the West. At the surface, a strong cold front will sweep across the central and southern FL Peninsula Monday morning and afternoon. While a thunderstorm or two cannot be ruled out across the FL Atlantic coast, deep-layer ascent will diminish as the primary ascent departs with the offshore trough. This will limit thunderstorm development inland as the expansive Arctic air mass forces the remaining instability offshore. ..Lyons.. 01/25/2026 Read more

Day 1 Convective Outlook CORR 1 NWS Storm Prediction Center Norman OK 1218 AM CST Sun Jan 25 2026 Valid 251200Z - 261200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE EASTERN GULF COAST STATES... CORRECTED FOR SUBSECTION HEADLINE ...SUMMARY... Severe thunderstorms are possible across parts of the eastern Gulf Coast states this morning and afternoon. Damaging gusts and a few tornadoes are the main concerns. ...Gulf Coast States... Southern Plains short-wave trough is forecast to eject across the Arklatex early in the period as a 100+kt 500mb speed max translates across northern MS, then increases to near 130kt over WV by 26/00z. Modest midlevel height falls will spread across the Gulf states and a strong LLJ will respond just downstream from northern AL into the Middle Atlantic. Associated polar front will surge into MS/southern LA by sunrise then shift into AL by 18z. Latest model guidance suggests modified Gulf air mass will advance inland ahead of the surging boundary such that weak buoyancy will develop within roughly 100mi of the Gulf coast. Forecast soundings suggest SBCAPE on the order of 500 J/kg could be noted prior to frontal passage where surface dew points rise into the mid-upper 60s. Given the deep layer shear, convection that develops within this environment would have some potential to organize with some supercell risk. For these reasons have maintained SLGT risk near the Gulf coast to account for morning-afternoon thunderstorms ahead of the cold front. Damaging winds and perhaps a few tornadoes are the primary concerns. ..Darrow/Thornton.. 01/25/2026 Read more

MD 0049 CONCERNING WINTER MIXED PRECIPITATION FOR NORTHERN LOUISIANA INTO EASTERN ARKANSAS...NORTHWEST MISSISSIPPI...AND FAR WESTERN TENNESSEE
Mesoscale Discussion 0049 NWS Storm Prediction Center Norman OK 0746 PM CST Sat Jan 24 2026 Areas affected...Northern Louisiana into eastern Arkansas...northwest Mississippi...and far western Tennessee Concerning...Winter mixed precipitation Valid 250146Z - 250645Z SUMMARY...Another round of freezing rain and sleet is expected to spread out of northern Louisiana into eastern Arkansas and northwest Mississippi. Freezing rain rates upwards of 0.05 inch/hour appear likely for some locations. DISCUSSION...Recent radar mosaics show a developing plume of precipitation across central to northern LA - likely associated with strengthening warm advection between 925-850 mb. Over the next several hours, an uptick in low-level winds should promote further augmentation of isentropic and frontogenetical ascent across the lower MS River Valley. Regional 00z RAOBs from SHV and LZK sampled a stout (4-12 C) warm layer between 850-700 mb that will melt hydrometeors as precipitation spreads north/northeast. Sub-freezing surface temperatures will promote some degree of re-freezing near the surface, though locations with temperatures at or near/below 15 F will likely be sufficiently cold (and have a sufficiently deep sub-freezing layer) to promote sleet as the predominant precipitation type. Warmer locations will likely observe freezing rain (with freezing rain rates up to 0.05 inch/hour) with periods of sleet possible. Based on latest surface observations, freezing rain appears most probable across southeast AR into northwest MS with sleet more likely for locations further north into east-central AR and far western TN. ..Moore.. 01/25/2026 ...Please see www.spc.noaa.gov for graphic product...
