Weather synopsis: June 8


4:20pm it has been a rather cool start to the work week for the most part across the Northeast. A storm system has pulled out of the region and in its wake a cool and dry air mass has moved in. High temperatures have been generally in the upper 50's to lower 70's with lows down in to the upper 40's in upstate New York and upper 50's along the coast. A new storm system will move infiltrate the region Wednesday; expect increasing clouds tonight in western New York with rain showers for tomorrow. The heaviest rain should remain south of Buffalo in to the Ohio River Valley; this storm system will progress east towards the coast and produce a steady rain fall for Pennsylvania then eventually the Hudson River Valley and southern New England. The rain will likely cease by early Thursday morning in the New York City metropolitan area. In the wake of this next system, temperatures should rebound nicely by Friday and down right hot by the weekend. A slight chance of showers and storms in the forecast in to the weekend with the greatest risk of storms likely on Sunday.

Weather synopsis: June 6




4:09pm a vigorous low pressure system is charging through the region. This storm system is dragging an sharp cold front. Ahead of the front temperatures are in the 90°F range; behind the front temperatures are in the 50°F range. This sharp difference in temperature is indicative of a very unstable atmosphere over the region. This instability has produced impressive amounts of rain over western New York yesterday with strong storms that have spawned a deadly Tornado outbreak over the Ohio River Valley and portions of the Midwest. Now this same system is plowing east towards the coast; Tornado watches have been posted from down east Maine to Washington D.C. Wind gusts of up to 80MPH are likely as a squall line of storms race eastward. Along with the damaging wind potential these storms could also produce golf ball sized hail and frequent cloud to ground lightning. Doppler radar indicate that these storms have been loosing strength, however portions of southern New England could still receive some severe thunder storms. Once this storm system pulls away expect a stretch of fair weather through the work week. Monday should be dry with cooler temperatures ranging between 65°F and 75°F. Temperatures will moderate this week but should remain around average with ample sunshine.
