10/17 – Rob’s “Autumn Arrives” Thursday Morning Forecast

0

The cold front that recently passed through now extends from central Florida to the western Gulf to an area of low pressure over Bay of Campeche. Cold air moving into the area will be strong enough to keep high temps about 5 to 7 degrees below normal today.

In the Gulf, a broad area of low pressure is forecast to move northeast to the northern and northeastern Gulf Friday into Saturday. Warm sea surface temperatures in the low to mid 80s and relatively light winds will give a short window for some development today. The upper level low pressure over Texas is expected to move over the south Louisiana and Louisiana coastal waters by Friday morning. Northeast wind flow and astronomical high tide will yield elevated tide levels late
tonight through Saturday. The close proximity will yield gusty winds and periods over heavy rainfall across land areas near the coast Friday and Saturday.

The system will continue to lift northeast and dry condition will occur across the area Saturday through Sunday. A vigorous low pressure system will track east across the Rockies late Saturday and Mississippi Valley Sunday night. This feature will drive a strong cold front through the forecast area Monday with possibly strong storms Monday day period. High pressure will build in the area next Tuesday and Wednesday.
