This week looks to be very busy! Temperatures will be below average throughout this forecast period. Tonight, clouds will begin to clear out as lows reach the mid 30s. Tuesday will be sunny with a high in the 50s. Tuesday afternoon will have a potential for showers that moves into the night. It will clear out again as we head into Wednesday with highs in the 40s. However, Wednesday night lows will dip below freezing. Clouds are expected to approach Thursday morning. This will set up the potential to have rain during the afternoon.

Technical Discussion (The nerdy stuff we are discussing in class!)
The 500mb NH plot shows 4 longwaves. One longwave trough remains over most of the CONUS this week. This longwave will have several weak shortwaves embedded that will effect the Midwest. These shortwaves will help provide us with precipitation chances this week. Our next chance of light precipitation will be Tuesday late evening into the overnight with a cold front to our north that moves through about 0600 UTC Wednesday. The winds Wednesday will shift to the north at the surface, filtering in cooler air with temperatures reflecting this. This will keep temperatures below average throughout the week. Next chance of precipitation arrives late Thursday afternoon into overnight Friday. Future forecasts will have to look at chances of precipitation changing to include a few snowflakes after midnight into Friday morning.
