Cool and (Mostly) Dry Conditions Ahead

Now that the disturbance that has dominated our weather for the past four days has moved through the area, cool and crisp air is moving into our area for the weekend. Additionally, post-frontal subsidence will allow for mostly clear conditions on Friday and Saturday. The peak of cold-air intrusion will occur Friday night into Saturday, as lows may reach the mid-20s in some areas early Saturday morning.

Temperatures will start to modify on Sunday, as extra moisture will start to move into the area. Currently, there appears to be a shortwave that will swing down from the Northern Great Plains into our area Sunday afternoon through Monday morning. At this time, while there will be significant cloud cover on Sunday into Monday morning, it does not look like precipitation will move into our area.

This shortwave will be the first in what appears to be a series of troughs that will swing through our area over the next week to ten days. Before the next trough swings through later next week, temperatures will continue to warm through the early part of next week, returning to near-normal levels by the middle of next week. Conditions look to remain dry and sunny at least through the middle to end of next week.

This map shows the path of various troughs that will swing through our area over the next week.
