Thunderstorms are not expected across the continental U.S. on Tuesday and Tuesday night. ...DISCUSSION... An upper-level trough is forecast to move eastward away from the East Coast on Tuesday, as west-northwest mid-level flow remains established across much of the continental United States. At the surface on Tuesday, an area of high pressure will be located from the southern Plains into the Mississippi Valley. Dry air advection associated with the high pressure system and relatively cold conditions across the nation will be unfavorable for thunderstorm development Tuesday and Tuesday night. ..Broyles.. 02/11/2024 Read more

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1246 AM CST Sun Feb 11 2024 Valid 121200Z - 131200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHEAST... ...SUMMARY... Organized thunderstorm clusters, associated with wind damage and a few tornadoes will be likely across parts of the Southeast on Monday. ...Southeast... An upper-level low will move into the mid Mississippi Valley on Monday, as an associated 90 to 110 knot mid-level jet translates eastward into the central Gulf Coast states. At the surface, a low will deepen and move northeastward into the southern Appalachian Mountains, as a cold front advances eastward across the central Gulf Coast states. At the start of the period, several bands or clusters of thunderstorms appear likely to be ongoing ahead of the front. These storms are expected to become organized as they move eastward across a moist airmass during the day. Surface dewpoints from near the front eastward to the southern Atlantic Seaboard will be in the 60s F, with weak destabilization taking place across the moist sector as surface temperatures gradually warm. The mid-level jet associated with the upper-level low will move eastward across Mississippi and Alabama during the day. The eastern edge of the mid-level jet is forecast to overspread the moist sector, which will create very strong deep-layer shear. Forecast soundings by 21Z from eastern Alabama into north-central Georgia have 0-6 km shear reaching the 80 to 90 knot range. In addition, the strong low-level shear already over the moist sector is forecast to be maintained, with 0-3 km storm-relative helicity values remaining in the 250 to 350 m2/s2 range. This shear environment will be favorable for severe storms, capable of producing wind damage and a few tornadoes. The severe threat is expected to continue through the late afternoon and early evening, as strong storms, associated with a potential for wind damage and a tornado or two, move northeastward into South Carolina. ..Broyles.. 02/11/2024 Read more

MD 0120 CONCERNING SEVERE THUNDERSTORM WATCH 15... FOR TX BIG COUNTRY INTO THE EDWARDS PLATEAU
Mesoscale Discussion 0120 NWS Storm Prediction Center Norman OK 1156 PM CST Sat Feb 10 2024 Areas affected...TX Big Country into the Edwards Plateau Concerning...Severe Thunderstorm Watch 15... Valid 110556Z - 110730Z The severe weather threat for Severe Thunderstorm Watch 15 continues. SUMMARY...The large hail threat is expected to increase overnight as storms move eastward. DISCUSSION...Elevated convection erupted earlier this evening from the western part of the Edwards Plateau into the TX Big Country, as an upper low approaching from NM began to impinge on the western portion of the primary instability axis. Increasing deep-layer shear will be supportive of organized convection overnight as convection moves eastward, and a few supercells may continue to evolve (like recent development south of Abilene and west of San Angelo) out of the ongoing elevated storm cluster overnight. MUCAPE increasing into 1000 J/kg and steep midlevel lapse rates will continue to support a hail threat, with very large hail of 2-2.5 inches in diameter possible with any stronger supercell. As long as storms remain semi-discrete and elevated, hail will be the primary threat, with perhaps some localized strong gusts. If convection can build into the southern portion of WW 15 closer to the surface boundary, then the threat may increase for a near-surface-based supercell, which would pose a conditional risk of all severe hazards. That scenario remains very uncertain at this time, however. ..Dean.. 02/11/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FWD...EWX...SJT...MAF...
