The remnants of Hurricane Willa in the Pacific Ocean is forecasted to move into the Gulf of Mexico and interact with a stalled front, bringing periods of heavy rain and well below average temperatures for the end of the week.
Willa will make landfall Tuesday evening and will quickly move across Mexico. By Thursday, the system will enter the Gulf of Mexico as a weakened area of low pressure. In the Gulf of Mexico, the remnant low will interact with a stalled front. The surface map shows the remnant low, stalled front, and the increasing moisture in the southeast on Thursday morning.
The low will track along the Gulf of Mexico coast and eventually up the eastern seaboard. Rain is expected to begin on Thursday Evening, with the heaviest rain ending Friday Night/Saturday Morning. Showers remain possible as moisture continues to wrap around the low pressure this weekend.
The heaviest rain is expected on Friday, especially during the daylight hours. The system will be moving relatively quickly, so the Weather Prediction Center shows 1-2 inches of rain across much of the southeast United States over the next five days. Widespread flooding is not expected to be an issue since the system will be moving quickly.
The other story will be the below average temperatures on Friday. With high pressure to the north bringing cold air from the Atlantic into the Carolinas and wedging it against the mountains, temperatures will be 20 degrees below average. Western and central NC locations are expected to remain in the 40s for high temperatures.
In the mountains, a few wet snowflakes are possible on the onset of the precipitation Friday morning. The best chance to see snow is above 4000 feet; however, with southerly flow, the snow is expected to change over to rain.
