Well, today is our sort of in between day, so to say. It has been cloudy for what feels like all of December, and it actually looks like we will be seeing some sunshine today! We’ll start today off in the upper 20s as skies will have cleared overnight, allowing temps to drop pretty far. This will give way to mostly sunny skies as we move into the day, and are influenced by an exiting high pressure system.
I would recommend enjoying this day, because changes are on the way…
After we see partly cloudy (albeit, increasing clouds throughout the day) skies and temps rising into the mid 40s, we will the beginnings of a more significant influx of moisture across the area beginning Sunday night. This will lead to thicker cloud cover as winds and atmospheric flow begins to shift to a southerly flow. Temps should drop into the mid 30s at the lowest because of the cloud cover, and may actually begin to rise late into Sunday night as the southerly flow increases. There may be an isolated shower or two, but that shouldn’t be too much of a problem.
Monday, 12/22: Partly to mostly cloudy skies, with some isolated showers. High of 57ºF. Mon. night: Cloudy skies, with rain entering the region. Low of 48ºF.
This is the day things really begin to get crazy. While Santa is still up north working on gathering the gifts and things, he will likely already be watching how this weather system will begin to develop to our north on Monday. As the atmosphere becomes more amplified, we will enter into southerly flow at the surface, and deeper southwesterly flow within the lower layers of the atmosphere.
With likely breaks in the clouds, this leads me to believe that temperatures are likely going to top out in the mid to upper 50s as we get into the afternoon. As moisture increases across the area, look for isolated light showers, but nothing too big. This is all out ahead of a developing low pressure system across the northern Plains.
As we move into Monday night, we will see rain begin to enter the region ahead of this low, and this will help to keep temps up overnight (in addition to the clouds). Lows shouldn’t drop further than the mid 40s, but will likely end up in the upper 40s, with winds increasing in strength as the night goes on.
Tuesday, 12/23: Rain chances increasing, and fairly windy. High of 61ºF. Tues. night: Rain and isolated thunder with low of 52ºF.
This will likely be the more active day this week. The low pressure system will begin to take on a duel-low characteristic, and new low pressure system will begin to intensify to our south. This will further intensify southerly flow across the area, and I think will warm temps above what guidance is showing now. However, it will be cloudy and rainy, which is a waste.
Because of the dynamics that this system will bring with it, we will likely be able to get some isolated thunderstorms within this system. Some heavier rain is looking likely as we head into the night as we see a major increase in moisture with this southerly low pressure system.
The wind fields look fairly decent, so if we can get a storm to tap those, there could be some isolated damaging winds. This system is gonna be really fun to watch from a meteorological standpoint!
