Update on both storms with snow maps, the brief cold and wind, warmth next week, and then what?

- You have the general idea for the snow today from all of my posts yesterday. The details for Long Island are below, but generally 0.5 to 1.5 inches with it starting as showers by mid-morning and then becoming snow for a few hours before changing to sleet and rain and then ending maybe as light sleet or snow showers in the evening. It could come down heavily for an hour or two between around 10:30 AM and 12:30 PM.

- Regarding the strong storm for Saturday, the GFS shifted eastward, so it's basically the same as the Euro now. The snow is still inland with rain for Long Island, but it should end as snow showers Saturday evening with little to no accumulation for Long Island. It will also become very windy later on Saturday and especially at night with gusts up to 45 mph from the NW, so a Wind Advisory will likely be needed. Overnight lows will be in the low 20's with the wind chill in the single digits into Sunday morning (3rd image), and highs on Sunday will only be in the upper 30's.

- It then warms up starting on Monday, and next week will be a mild week.

- However, snow can't be ruled out after March 22nd.
