Mostly cloudy and mild tonight with a 20% chance of showers. Lows will be near 70. Winds should be from the south at 10-15 mph.
Tomorrow, we should have mostly to partly cloudy skies and a 40% chance of showers or thunderstorms--turning cooler late in the day. Highs will range from the mid-70's in Galveston to near 80 on the mainland. We anticipate southwest winds at 5-10 mph, becoming northwesterly at 10-15 mph later in the day.
On Thursday, look for partly cloudy skies, breezy conditions and cooler temperatures. Highs will be in the mid-60's. Expect northeast winds at 10-20 mph.
SHORT -TERM OUTLOOK:Partly cloudy skies and mild temperatures will continue today ahead of a cold front expected to reach the coast late tomorrow. We will see a slight chance of showers tonight and a chance of showers or thunderstorms tomorrow as the front rolls through, followed by clearing skies and cooler temperatures tomorrow night.
NATIONAL OUTLOOK:This morning we find a couple of cold fronts to our west and northwest, with one front extending south from a low near Las Vegas to the Pacific. A second front extends east from that low to other lows in southern Colorado and eastern Nebraska. A winding warm front bends southward from the Nebraska low along the Mississippi River and then east-northeastward to the Carolinas. Further north, a slow-moving cold front stretches all the way from northern Oregon to lows in Montana, Minnesota and Canada near Hudson Bay. Finally, a 5th frontal boundary extends east from the Great Lakes across New England to the Atlantic.
At the upper-levels, we continue in a mostly zonal west to east flow with a broad weak high pressure ridge over the eastern half of the country and a modest low pressure trough over western third of the U.S.
Mild conditions, partly cloudy skies and a slight chance of showers tonight will prevail today. Tomorrow should bring partly to mostly cloudy skies with a fair chance of showers or thunderstorms as a cold front moves through the area. This will lead to breezy conditions and cooler temperatures for the last half of the week. Rain chances will increase again this weekend as a surface low and upper-level disturbance combines with deep moisture levels to bring showers and thunderstorms to Southeast Texas.
Tropical development is not currently expected in the Atlantic Basin.
