1/19 – Brittany’s “Gorgeous” Thursday Evening Forecast

Cold front has cleared the CWA and continues southward into the Gulf of Mexico. Post frontal surface ridge will be building in today as well as Friday. This will keep rain chances out of the forecast and start the upcoming cooler temp trend. Guidance is pretty tight in terms of highs and lows, so made no changes from the deterministic NBM which has lows mainly in the 40s tonight and highs in the lower to mid 60s Friday. Both of those values are roughly near normal for this time of year.

Cloud cover will be on the increase again by Friday as the post- frontal surface high situated over the mid Mississippi River Valley moves off to the east and a trough of low pressure develops along coastal TX. Winds will flip from northerly to the east then southeast by Saturday. In the upper levels, a low coming across the Rockies will be absorbed by another trough dipping out of Canada and this combined trough will track across the upper/mid Mississippi Valley Sunday. This trough will aide in lifting moisture northward through the afternoon on Saturday yielding high chances of rain across much of the area. The period if light to moderate rainfall will be longer than a quick frontal passage as the merging of the 2 features above will slow down the overall eastward progressing. Thus, light stratiform rain could linger into Sunday before gradually waning by the evening as the low and associated trough exits the area. Temperatures during this dreary period will be in the upper 50s to low 60s during the day and mid 40s to low 50s at night.
