Severe thunderstorms are not expected on Friday. ....Synopsis and Discussion... A belt of enhanced westerlies is forecast to extend from the Canadian Prairie Province eastward across Ontario and southern Quebec into New England throughout the day on Friday. A shortwave trough embedded within these westerlies is forecast to progress quickly eastward across Ontario and Quebec and adjacent portions of the Upper Midwest and Upper Great Lakes. An associated surface low will move across Ontario just ahead of this shortwave, with an attendant cold front pushing southeastward across the northern/central Plains, the Upper/Mid MS Valley, and the Upper Great Lakes. Scant low-level moisture is expected ahead of this low, limiting the thunderstorm potential along most of the front. Some modest buoyancy may develop across the Upper Great Lakes region where low to mid-level moisture is expected to increase amid cooling mid-level temperatures. This may result in deep enough updrafts for a few lightning flashes between 18Z and 00Z. Farther south, a low-amplitude shortwave trough is expected to drift southeastward from OK into the Lower MS Valley. Cold mid-level temperatures will accompany this shortwave, and lingering warm-air advection showers and thunderstorms may result in a few lightning flashes across eastern OK and northeast TX Friday morning. Lastly, upper 60s to low 70s dewpoints are expected to persist across central and southern FL throughout the period. Some showers are likely throughout the day amid confluent low-level northeasterly flow. However, warm temperatures aloft will limit storm depth throughout much of the period across the region. The environment across south FL is expected to become more conducive to deep convection late Friday night/early Saturday morning as mid-level temperature cool slightly and low-level flow trends more southeasterly. Consequently, a few flashes are possible across south FL and/or the Keys after 00Z. ...Mosier.. 10/10/2024 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
