SYNOPSIS AND OUTLOOK:Relatively dry air over Southeast Texas will bring us mostly sunny to partly cloudy weather through Saturday with morning temperatures slightly cooler than what we have seen and with seasonably hot afternoons.
This morning, a stationary front extends from the south-central Gulf of Mexico northeastward across north Florida into the Atlantic. To the north, a surface low is located over eastern Nebraska with an associated cold front extending southwestward from the low across Kansas, the extreme northern Texas Panhandle and New Mexico. High pressure is building behind the front over Wyoming and high pressure is also situated in the East over Pennsylvania. In the West, low pressure is located over Washington state and Southern California while a Pacific cold front is moving east towards Oregon and Washington.
At the upper-levels, we are seeing an amplified pattern with a large high pressure ridge extending north and northwestward from Texas and the Desert Southwest to the Great Basin region and the northern Rockies. To our east, a low pressure trough extends southwest from the Ohio Valley to the Southeastern U.S. and Gulf of Mexico.
Moisture levels and clouds will gradually increase over the weekend as southerly and southeasterly winds prevail. Looking further ahead, an upper-level low is expected to form over the Gulf of Mexico and the Texas coast by early next week, bringing us another chance at rain.
Tropical Storm Erika is racing west-northwestward through towards the Dominican Republic this morning.

A Tropical Storm Warning is now in effect for U.S. Virgin Islands, Puerto Rico, Hispaniola, and the southeastern and central Bahamas. A Tropical Storm Watch has been issued for the northwestern Bahamas.
Otherwise, storm development is not expected in the Tropical Atlantic Basin at this time.
