Subj : DAY1SVR: Day 1 Convective Outlook To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Tue Jul 23 2024 01:03:15 ACUS01 KWNS 230103 SWODY1 SPC AC 230101 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0801 PM CDT Mon Jul 22 2024 Valid 230100Z - 231200Z ....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER SOUTHERN AND EASTERN NORTH CAROLINA...CENTRAL AND EASTERN NORTH DAKOTA...AND WESTERN ARIZONA... ....SUMMARY... Isolated severe thunderstorms remain possible early this evening over portions of North Dakota, southern and eastern North Carolina, as well as western Arizona to the lower Colorado River Valley. ....North Dakota... A small cluster of strong/severe thunderstorms continued moving south across eastern ND at 01z, with a history of severe hail and wind gusts. A weak mid-level impulse continues to provide subtle large-scale ascent as it moves southeast near the international border, and the downstream environment will remain strongly unstable for the next few hours. With around 30 kts of deep-layer shear, sufficient storm organization is expected to persist for a continued severe threat through the remainder of this evening. ....Western Arizona and Vicinity... Scattered thunderstorms continue moving generally south within a weakly buoyant environment with a well-mixed boundary layer (LCL heights over 3500 meters). Storms have not shown a tendency to cluster thus far, however any merging outflows that can develop will have severe wind potential through this evening. ....Mid-Atlantic... Have trimmed the Marginal Risk and associated wind/tornado probabilities to in the immediate vicinity of the storms extending from near Elizabeth City (KECG) to Clinton NC (KCTZ). Latest mesoanalysis shows moderate bouyancy and 30-40 kts of shear in the near-storm environment. Occasional weak/transient cyclonic shear has been noted in a couple of these storms, and effective SRH of 100 m2/s2 would support some continued (though low probability) risk for a brief tornado or gusty winds this evening. ...Bunting.. 07/23/2024 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
