Public weather briefing
After a lovely Thanksgiving weekend Madison was greeted with a dreary Monday, filled with scattered rain showers. Unfortunately (or fortunately, depending on your precipitation preference for December 1st) winter storm Delphi passed to the west, dumping snow on much of Minnesota and the Dakotas, but only clipping northern Wisconsin. Once this system moves out, moderate December temperatures will move in. Temperatures will consistently reach the mid 40s during the day and hover around 30 at night. There will be little hope for snow in the upcoming week.Forecast
Tonight. Mostly cloudy with lows around 30. Slight chance of rain/snow mix with minimal accumulation.
Wednesday. Mostly overcast with light winds. Highs in the mid 30s.
Wednesday night. Clouds clearing overnight. Lows in the upper 20s.
Thursday. Sunny and slightly warmer. High around 40. Low around 30.
Friday. Continued sunny. Highs in the low 40s.
Outlook for Saturday and Sunday. Saturday will be mostly sunny and the temperature could reach close to 50. Sunday will be comparable, only slightly more cloudy and reaching the mid to upper 40s. Each night will dip down to around 30. [CONFIDENCE: MEDIUM]
Forecast Discussion
Winter storm Delphi showed some interesting development. The storm is characterized by a cold pool of air that has been sequestered from its origin in Canada due to a thermal ridge. The same circular region exhibited high vorticity, as the jet pattern across the US wrapped itself around the cyclone.
The storm will continue to move through the Northern Plains/Upper Midwest for the rest of the day, bringing sizable snowfall to many of our neighboring states. The cold front associated with Delphi might bring minor precipitation to our area tonight, but it would be a rain/snow mix - nothing like others have seen from this storm.
Once the cold pool moves out of our area on Wednesday evening, we will see uniformly sunny and moderately warm days through the rest of the week. Much of the Midwest will be located in a thermal ridge, bringing us these relatively warm temperatures for the first week of December. We will also be located in a broad anticyclone, with minimal expectations for precipitation, rain or snow.
