SYNOPSIS AND OUTLOOK:Colder than normal weather continues over Southeast Texas behind a strong cold front as high pressure builds in over the region. This will lead to partly cloudy skies and gradually decreasing wind speeds. Clouds will begin increasing on Saturday as a surface trough and low begins to form in the western Gulf of Mexico.
This morning, a strong cold front extends south from the Big Bend area deep into Mexico to near Vera Cruz. The front then continues east-northeastward across the southern Gulf of Mexico to Florida and a low in the Atlantic south of Bermuda. A large region of high pressure is located behind the front from Pennsylvania to North Texas. High pressure also sites over most of the Rocky Mountain region. A surface trough is located over New Mexico and southeast Colorado with a warm front over the eastern part of the central and northern Plains.
At the upper-levels, we seeing a somewhat more amplified flow with a broad high pressure ridge off the U.S. East Coast, a weak low pressure trough digging southwest from the western Great Lakes and northeastern Plains. Further west, a strong high pressure ridge is located along the West Coast, while a low pressure trough is developing to the south near Baja California.
Partly cloudy skies with cold nights and cool afternoons will prevail through Saturday. We will see increasing clouds on Saturday and Saturday night with rain chances appearing on Sunday as a surface low and trough develop in the northwest Gulf of Mexico and the upper-level low pressure trough to our west deepens. Rain will continue into Monday, with fairly substantial amounts possible before the system in the Gulf moves off to the northeast.
The Tropical Atlantic Basin continues to be quiet overall with no active tropical cyclones and tropical development not expected over the coming 48-hours.
