Sunny skies will boost temperatures to near 40 today. It will be a very nice day, similar to the end of yesterday which featured clearing skies and light winds. Tonight, temperatures will drop to the coldest we've
Tomorrow will see increasing clouds out ahead of a strong storm in the Great Lakes region. Highs will be forced down a little in the mid 30's. Snow will enter the region early Friday morning, and fall heavily at times through 10am. The low Friday morning will be in the mid 20's. Precipitation will change to freezing rain late Friday morning and continue through 4pm. The storm will end with a change back to a sleet / snow mix. My current snow accumulation forecast is 4 to 7 inches plus around a quarter inch of icing possible.
Temperatures will probably reach the highest for the week on Saturday. Temperatures will rise out ahead of the Great Lakes low into the low 40's. The average high for 3/3 is 38F. A high temperature of 42 would tie for the highest since January 13th when highs reached 48F.
There is even a chance of showers on Saturday as a weak frontal boundary crosses the region. This chance will continue through Saturday Night as snow showers.
Sunday, temperatures will fall back a little, into the upper 30's. Much colder air arrives Monday and Tuesday as highs stuggle to reach the low 30's and upper 20's respectively. Another weak disturbance (bringing also reinforcing cold air) could bring a chance of snow showers to the region Tuesday, but that chance is minimal so I didnt include it in the forecast.
Long term:
The new cold will last through next weekend, before a developing positive AO and NAO send temperatures averaging 4 to 7 degrees above average through the end of March. See yesterday's post for more details.
