Update on the Next 3 Storms (Including Snow) for Long Island
See the "My Personal Weatherman" Facebook page for frequent updates.
- Temperatures are in the upper 50's this morning on Long Island. There won't be much rain this morning, but showers will move in this afternoon and the temperatures will begin to fall. The rain should change to snow on Long Island around 3 AM to 4 AM early tomorrow. It should end mostly from around 11 AM to Noon from west to east. Still expecting around 2 inches or so with isolated 3 inch totals. - A Winter Weather Advisory has been issued for tomorrow morning for Long Island, CT, RI, and southeastern MA. While snow totals may be marginal in some areas, the timing of the snow during the morning commute affected the decision by the NWS to issue the advisory. - The change for this storm is that the snow has shifted to the southeast a little, so expect a pretty sharp cutoff up in MA and northwest CT. While the National Weather Service maps don't truly reflect this, the snow maps from the HRRRv4, NAM, Euro, and Euro ensemble mean are all showing this.
- The rainstorm for this weekend will mostly be Friday night (after 9 PM possibly) into early afternoon Saturday on Long Island. Expect 1 to 2 inches of rain, gusty winds, and minor coastal flooding. I will have more details going forward.
- The Euro is showing a snowstorm next week from Tuesday afternoon into Wednesday morning on Long Island and southern New England. More of the Euro ensembles are starting to show it, but it's still fairly low confidence for now, at least for Long Island. More confidence in an all snow event for MA.
