Winter making a return?

April openned with sunny skies and record setting highs in the 80's across New England. This supposedly marked the end of a disappointing winter for the region. However, old man winter is making a last appearance at the end of the week.

A shortwave will swing down from Ontario Thursday Night. A secondary surface low will develop south of New England with a strong cold front extending NW to SE across NY and NJ. The frontal boundary will be a focus for moderate precipitation for much of New England during the day Friday. Model QPF totals are projected around .75"

Precipitation type becomes a concern as high pressure to the north allows a cold northerly ageostrophic flow. At least some mixing with snow appears likely for interior high terrain of New England. In fact, there is growing agreement for decent accumulation. Given the time of the year, it's definitely wise to stay cautious with these situations. We'll have to watch it closely however, because a surprise late season moderate snowfall is entirely possible.
