Update on cold, snow, and the weekend as this will be the last cold week as next week looks mild:
The storm out in Colorado and Wyoming was as advertised as I saw reports of snow amounts over 50 inches. You can see the impressive look of the storm from the satellite image from last night!
The 2nd image shows the severe weather potential in the deep south for Wednesday.
The details for Long Island are in the forecast below, but it will be very cold today into tonight as lows again by tomorrow morning will get into the teens in parts of Long Island. The weak system for tomorrow night into Wednesday morning will bring some snow showers changing to rain showers. Rain develops Thursday late afternoon or evening and probably ends as wet snow Friday morning or early afternoon with no accumulations, but it will be windy Thursday night into Friday with gusts possibly up to 35 mph from the tight pressure gradient between the storm and the high pressure to the north.
The weekend looks mostly sunny and then it looks milder again for next week with highs mostly in the upper 50's on Long Island.
