First Warning Weather
HOT & HUMID FIESTA DAYS
We will see an increase in clouds overnight as southerly winds increase ahead of an approaching upper level system. Forecast models show a few storms developing to the west and moving into area late tonight. Conditions will favor storms reaching severe levels. Temperatures will drop into the mid 60s by Thursday morning under cloudy skies. Skies will break near noon as temperatures rise into the upper 70s. A Pacific cold front will push into the area Thursday afternoon. I am not expecting much action with this front. The main upper level support will be too far north and temperatures in the middle part of the atmosphere will be warm. These two factors will make for isolated strong storms along the front as it moves into deeper moisture east of San Antonio. Look for dry air to filter in behind the front. Afternoon highs will approach 90 degrees.
The next upper level system will approach the west coast on Friday. Meanwhile the Pacific front will become a tropical warm front and head northward across the region. This will take Gulf moisture deep into the state. The combination of afternoon heating and dryline to the west will set the stage for a few showers to develop out west. Friday morning will start out in the mid 60s with afternoon highs approaching 90 degrees. Rain chances will begin to increase as the west coast storm moves onshore and into Arizona by Saturday morning. Storms will likely develop out west. Upper level winds from the west coast storm will steer the storms into our part of the state late Saturday night into Sunday morning. Another Pacific front will move into the region on Sunday bringing rain chances. The upper storm will move into the Plains states on Sunday and into the Ohio Valley on Wednesday. Temperatures will stay above normal into Tuesday. Another cold front will help cool things down by next Wednesday. Join Shaun Stevens tomorrow morning on Fox News First. He'll let you know what to expect for the Fiesta parades.
