Discussion:

After a week of very beautiful and benign weather, the possibility for rain will once again return to the area. A weakening and dry cold front has  passed our area this morning and dry air will filter into the area throughout the day. Therefore, will have two more pleasant days in the mid 70’s before clouds begin to increase throughout the day Tuesday in association with an approaching cold front. Light to moderate rain showers will accompany this into the evening and overnight hours. Locally heavy showers are possible with a few rumbles of thunder, but nothing severe is anticipated due to the lack of instability and the timing of the frontal passage. The cold front is projected to pass our area during the early to mid-morning hours on Wednesday. With this said, precipitation will quickly slack off before noon and clouds will begin to clear throughout the day.

NAM 12Z (7am CDT) Wednesday morning Mixing Ratio and 10m wind vectors representing atmospheric moisture and its transport or advection. Notice the drastic wind shift over our area denoting the cold front with much drier air projected to filter in throughout the day Wednesday.

With the drier and cooler air in place, a beautiful Thursday should be in store with temperatures barely cresting 60 degrees under sunny skies. A jacket is advised with morning temperatures starting in the lower 40’s.
