Last week temperatures were below normal again, by 2 to 4 degrees across most of the state. Precipitation ranged from less than ¼ inch in western NY to over 1 inch in a few isolated areas. Base 50 growing degree-days ranged from near zero to over 20.
Warm & dry Thursday, then turning cooler & unsettled…
Today high pressure will provide dry and sunny conditions. Temperatures will be above normal, throughout the 70’s and some areas reaching 80. Afternoon thunderstorms are possible in western areas as a cold front approaches and will bring overnight showers moving west to east over the state.
Overnight lows will be in the mid 40’s and 50’s.
Friday will be cloudy with rain likely as the cold front passes. Highs will be in the 60’s, with some low 70’s. Eastern areas of the state will warm before the front moves in. Lows will be in the mid 40’s to low 50’s.
Saturday will be cloudy with showers as another cold front moves through. Temperatures will be in the mid 50’s to low 60’s, eastern areas will reach upper 60’s. Overnight temperatures will be in the mid 30’s to 40’s with light wet snow possible.
