Cool Weather Continues

The start of the Spring season has turned out to be dry but on the cool side. Today's highs reached the mid to upper 50s and it looks like we won't reach those values until late this week. High latitude jet stream blocking will occur downstream from the northeast which will lead to cooler than average conditions for the Northeast and mid-Atlantic. A back door cold front (a front which approaches from the north or northeast) will slide through tonight bringing just a few clouds and a Canadian air-mass for early this week. Abundant sunshine will prevail but the northerly winds will keep temperatures cooler in the upper 40s to low 50s through Wednesday. Temperatures will moderate some by the end of the week approaching the low 60s before another cold front slides through late in the weekend. Expect a small chance for showers on Thursday and then a better chance with the cold front passage for next Sunday. I expect overall temperatures to remain below average through the month of March into April as the downstream jet stream blocking continues.
