1/1 – Rob’s “Clear and Cool” Tuesday Morning Forecast
Surface high-pressure extended from Illinois to east Texas. This high-pressure will shift eastward today and Wednesday. Expect sunny skies and cool temperatures today with winds continuing from the NNE. The disturbance over New Mexico will gradually move Eastward. This should produce a few light showers early Wednesday morning as mid and upper clouds will move across eh area.
A northern disturbance is expected to move through the area Thursday with few impacts. Northerly surface winds Thursday into Friday will help to advect cold air and dry air into the area. As we move into the weekend, another upper level disturbance is expected to move through the area. Looking at the models, no rain is expected on Friday, but surface winds will turn southerly Friday afternoon. This shift will allow moisture and warm air to be reintroduced to the area. Weak upper level divergence will allow for some lifting in the environment as well, especially Scattered showers will be possible with this frontal system moving through. Overall, it looks fairly weak and severe weather is not expected. The models are still really uncertain on the timing and strength of the system.
Behind the front on Sunday, high-pressure will return to dominate the area. Northerly surface winds will act to help cold air and dry air advection into the region. Low temperatures on Sunday will be in the upper 30s to low 40s for most of the area.
