March chill may last to the end of the month

As Meteorologist Kristin Cwynar mentioned in the previous post, temperatures the past few days have been falling short of average.  Highs Wednesday reached the low 30's, still about 10 to 15 degrees below average but warmer than Tuesday. 

Temperatures will continue to warm through the week with highs back to, and slightly above, average by the weekend.  But the 6-10 day and 8-14 day outlook from the Climate Prediction Center suggest temperatures over the Midwest, Great Lakes and Northeast may have a higher probability of staying slightly below average.  A different end to the month of March than what happened at the end of January and February. 

While signs of a major cool down (like the one we had Tuesday and Wednesday) are not on the horizon, high temperatures may continue to remain just a few degrees below normal through the end of the month.  Normally we should be in the middle and upper 40's.

A fairly progressive jet stream will remain in place over the United States making it difficult for blocking patterns to develop, which is what brings the extreme warmth or extreme cold.  This fast moving jet stream will also increase the chance for Pacific storm systems to traverse the country, bringing an above average chance for precipitation.
