Through tonight: It will be dry through the period. The southern branch of the jet stream will remain overhead but the latest surface analysis had a >1020mb high centered over the southern Great lakes region. This high will shift east through tonight but continue to ridge back across our CWA from the northeast. Together these features will result in dry weather but also continued warmer than normal temperatures. /22/
Wednesday-Monday:
The National Hurricane Center is currently monitoring an area of disorganized showers and storms associated with a trough over the far southwestern Gulf (i.e. Invest 92L). Global models are in agreement that this area of convection will become better organized later this week, with NHC holding at an 80% chance of tropical cyclone development at this time.
WPC has added an for "Slight" risk of excessive rainfall across the CWA associated with future tropical cyclone development. As a result, an areawide "Limited" flooding HWO graphic will be issued this forecast cycle. It's too early to determine exact rainfall totals and impacts this potential system will have on the gulf coast or our forecast area. Residents and visitors to the region should monitor the latest forecast for the most up-to-date information. Outside of tropical cyclone development, deep tropical moisture will bring rain chances ranging from 30-50% over the weekend. /19//SW/
