Well, the second round of wintery weather we mentioned early this morning has certainly come to fruition. It is also looking quite healthy on radar, much of what is showing as mixed precipitation on radar is now falling as a mix of snow and sleet. Roads wet from today’s mixed precip and rain will quickly become slushy and snow covered. If the intensity of this band can keep up and it also persists as long as guidance has suggest we may be looking at a few heavy wet inches of snow over the next several hours. Based on current observations and radar it appears that Columbia, Greene, Ulster and Dutchess may be the areas of biggest concern for the best accumulating snowfall. Keep those observations coming and we will as always be keeping you all one step ahead of the weather.
The band of precipitation discussed this morning, is developing quite nicely at this hour. The flow around the nor’easter continues to be out of the east, which is causing this precipitation shield to move opposite the usual direction… from east to west. Because of the location of the low pressure at this hour, the shield of precipitation should stall out over the Hudson Valley. That means our area could see another extended period of precipitation… with guidance suggesting it could last until 9 or 10pm in some areas.
For the next few hours, expect periods of light rain, mixing with sleet and snow… gradually becoming more of a mix of sleet and wet snow after dark. The precipitation could be steadiest east of the Hudson River, but slick conditions are possible across the entire Hudson Valley. Accordingly… Winter Weather Advisories remain in effect for all areas except Rockland and Westchester counties. We’re watching areas east of the Hudson River especially close, as the data is suggesting the possibility of some snow accumulation after dark.
Wow, what a night it has been across the region, one of the more impressive sleet storms to impact our region, we are now in out 12th hour of heavy sleet across the region. Anywhere from 1″-5″ of sleet has fallen across the region, roads are treacherous and multiple accidents are being reported and power outages. Strong winds continue to impact the non sheltered parts of the region, as you can see from our station in NW Ulster County, winds have been increasing all night with gusts near 30 MPH.
Mostly rain has fallen across our southern zones as expected although we have seen some periods of sleet, as you head north and west it has been a pure sleet storm. Latest radar and short range forecast models show the steadiest precipitation pushing out of the region from SE to NW over the next few hours.
Our storm has not yet departed at this point but has shed its moisture shield, we will still remain under the influence of the Nor Easter, gusty winds, scattered rain, sleet and snow though the morning and afternoon. You can see the approximate location of our storm system at 10am and its strong wind field.
You can clearly see the barometer at our NW Ulster County station showing the low pressure continuing to near our region this morning and will likely bottom out in the next few hours…
Our eyes will then turn to the possibility of the low pressure helping to set up a new deformation band over the region later this afternoon and evening around the commute. Most short range guidance shows this possibility. Temps at this time at both the surface and at about 5000 feet look less impressive, so this may be a period of rain, we need to make sure this doesn’t fall as snow, sleet and freezing rain in parts of the region for a second round that linger into the late evening. This storm will be slow to depart, its effect will be felt into Wed, put the worst of the steady precip is getting ready to depart, heres a look at that second band later today.
So we have covered alot, but we haven’t left any stone unturned with this system and this update takes us though what the final evolution and departure of this nor easter should look like. Expect continued impacts in the form of scattered precip and blustery conditions, we are monitoring a second round of steady precip for later this afternoon and evening, steadiest precip departing this morning. Please stay tuned for further updates and thank you for trusting HVW!
