Subj : DAY1SVR: Day 1 Convective Outlook To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Tue Jan 30 2024 05:22:17 ACUS01 KWNS 300522 SWODY1 SPC AC 300520 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1120 PM CST Mon Jan 29 2024 Valid 301200Z - 311200Z ....NO THUNDERSTORM AREAS FORECAST... ....SUMMARY... Thunderstorm probabilities are very low today. ....Southern Arizona... Weak large-scale troughing will extend across northwestern Mexico into the Four Corners region today well ahead of the primary upper trough expected to approach the West Coast late in the period. Latest model guidance suggests strong boundary-layer heating will occur across northwestern Mexico into southeast AZ where surface-3km lapse rates will steepen in excess of 8 C/km. This will likely lead to weak buoyancy by afternoon, but higher PW air mass will hold south of the international border, along with greater instability. Forecast soundings suggest surface-based parcels will be negligibly inhibited by 21-22z, and only isolated showers are expected within a weak-flow regime across this region. While a lightning strike can not be ruled out with the deepest updrafts, the primary risk for thunderstorms should hold south of the border. ...Darrow/Wendt.. 01/30/2024 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
