AREA FORECAST DISCUSSION National Weather Service Albany NY 825 AM EDT Thu Apr 22 2021

SYNOPSIS. Unseasonably cold and brisk conditions today along with some snow and rain showers. Friday will feature sunshine and warmer temperatures near seasonable levels. Above normal temperatures for Saturday with clouds on the increase during the afternoon and evening as storm approaches. A widespread rainfall will occur Saturday night into Sunday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Updated at 815 am. Issued a quick update to the forecast this morning along with a special weather statement to cover for some more significant lake effect snow bands that have developed from the northern Catskills southeast across the Hudson Valley into the southern Berkshires and northern Litchfield county Connecticut. Areas affected by the most persistent bands in this region could see up to an inch or two of snow through about 10 am. The band is not only affecting higher terrain but also the Hudson Valley around Hudson and is causing slick travel in that area. We have reports of a few accidents on the Berkshire spur going into Berkshire county. The trend should be for these bands to break up into more scattered snow showers later this morning as strong late April sun increases the instability and decreases the organization of the bands. Until that happens however there will be narrow areas of more intense snow and accumulations. Previous discussionn is below.

Unseasonably cold and brisk today with some snow and rain showers.

Temperatures will run 15 to 20 degrees below normal for this time of year as the an anomalously cold air mass was ushered in the region with the passage of strong cold front Wednesday afternoon. The system has become vertically stacked and will continue to deepen today as it moves gradually into the Canadian Maritimes. It's associated cold poll will move directly over the region today and additional short waves will rotate about the system keeping the threat for snow and rain showers in the forecast through the day. Aiding the chances for showers and cloud cover will be the favorable flow of the cold air across the Great Lakes.

The region will be squeezed between the stacked system and an advancing high. Westerly winds will increase to 15 to 20 mph this morning with gusts of 30 to 40 mph. The strongest winds will occur down Mohawk Valley across the Helderbergs and Capital District into the Taconics and Berkshires. Expecting gusts to remain below 46 mph criteria for a wind advisory. Extensive cloud cover will help limited stronger gusts.

SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/. Moderating temperatures with a return to spring-like weather.

Brisk conditions will persist through Friday as the region is between the departing storm and an advancing high. Winds will weaken tonight but will pick up and becoming gusty Friday morning. Westerly winds of 10 to 20 mph with gusts of 25 to 35 mph are expected.

Cloud cover will decrease tonight with sunshine returning Friday as ridging begins to build in at the surface and aloft. Tonight will be another chilly night with dropping down in the mid 20s to lower 30s. Despite the chilly start, temperatures are expected to rebound to near normal readings Friday afternoon with highs in the 50s below 1500 feet, in the lower 60s in the mid-Hudson Valley and in the 40s above 1500 feet.

Temperatures will warm even more Saturday with above normal readings by around 5 degrees. Looking at highs in the 60s below 1500 feet and in the 50s above that. Sunshine to start the day with clouds on the increase during the afternoon as ridging shifts eastward and its gets surpressed by approaching short waves and their associated lows.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. Long term forecast looks to start out wet for the second half of the weekend, but conditions improve to start the work week. Temperatures should rebound nicely through the first half of the week, with highs climbing into the mid and upper 70s for Wednesday and Thursday. Details below .

Main concern for this period is the potential for a coastal storm Saturday night through Sunday afternoon. As upper-level ridging and surface high pressure move east, a northern stream disturbance approaches from the west and a southern stream shortwave moves northeastward from the southeast U.S. The degree of interaction between the northern and southern stream still remains uncertain, with the CMC being an outlier with little phasing. However, given GFS/ECMWF consensus on a partial phase, am leaning towards a wetter solution for the weekend, which is supported by ensemble guidance. Less interaction between the northern and souther stream would lead to a drier solution for our area, while more phasing could lead to heavier QPF amounts than currently predicted, so will continue to monitor model trends over the next few days. With wet conditions expected Sunday, expecting temperatures to be mainly in the 50s across the region.

As the surface cyclone pulls away from the region Sunday evening, we will be in a cold advection regime through the day Monday, which should keep temperatures a few degrees below normal. Monday does look mainly dry, however, as heights rise aloft and high pressure begins to build towards the region.

A warm front looks to move northward through the region Monday night or Tuesday morning, but is not expected to bring us any precipitation. From this point forwards, surface high pressure and ridging aloft will dominate the remainder of the long term pattern. While a series of weak upper level disturbances may move over the ridge and result in some increased cloud cover from time to time, moisture looks to be lacking so therefore expect our region to remain dry Tuesday through Thursday. With a warm advection regime taking over, temperatures should climb into the upper 60s on Tuesday, with high temperatures potentially reaching the mid and upper 70s Wednesday and Thursday, which would be 10-15 degrees above average for this time of year. With southwesterly winds, it would not be out of the question to see a few 80 degree temperature readings in areas that downslope off of the Catskills.

AVIATION /09Z THURSDAY THROUGH MONDAY/. A band of snow showers is currently from Herkimer County through the Capital District into Litchfield County CT. These snow showers are currently moving to the southeast and could briefly impact KALB and KPSF over the next couple hours with some light snow or snow showers and reductions to MVFR visibilities.

For the rest of tonight, expecting mainly MVFR to VFR ceilings at all TAF sites. Expecting mainly cloudy conditions through the day tomorrow, with ceilings around 4000 ft during the morning increasing to 6-7K ft through the afternoon. Some pop-up rain and snow showers are likely through the day tomorrow, so have included VCSH at all TAF sites through the day tomorrow and PROB30 for rain and snow showers at GFL, which has the best chance at seeing some precipitation. If one of these rain/snow showers moves over one of the TAF sites, would expect a brief reduction of visibility to MVFR conditions. Showers diminish after sunset tomorrow, with just a few to scattered clouds in the 6-10k ft range expected through 6Z Friday.

Winds will be gusty out of the NW tonight and tomorrow. Expecting winds to increase to 20+kt after sunrise tomorrow, with the strongest winds occurring during the afternoon. Would not be surprised to see some gusts 35-40kt at KALB and KPSF between 18z tomorrow and 00z Friday. Winds will diminish after sunset tomorrow, but will remain breezy from the west at around 10kt with gusts to 15- 20kt possible especially before midnight.

Outlook .

Friday Night: No Operational Impact. NO SIG WX. Saturday: No Operational Impact. NO SIG WX. Saturday Night: High Operational Impact. Likely SHRA. Sunday: High Operational Impact. Breezy. Likely SHRA. Sunday Night: Low Operational Impact. Breezy. Slight Chance of SHRA. Monday: No Operational Impact. NO SIG WX. Monday Night: No Operational Impact. NO SIG WX. Tuesday: No Operational Impact. NO SIG WX.

AVIATION /13Z THURSDAY THROUGH MONDAY/. Current radar shows scattered snow showers across the region. Most TAF sites have avoided the snow so far, although some upslope enhancement has resulted in periods of snow at KPSF over the past several hours. Light snow will likely continue at KPSF for the next couple hours before becoming more scattered in nature through the rest of the day.

For today, expecting mainly VFR ceilings at all TAF sites with the exception of KPSF where MVFR conditions are expected through the next few hours. Skies will remain mostly cloudy today, although ceilings will likely lift into the 5000-7000 ft range after noon today. Some pop- up rain and snow showers are likely through the day, so have included VCSH at all TAF sites through the day today. If one of these rain/snow showers moves over an airport, would expect a brief reduction of visibility to MVFR conditions. Showers diminish after sunset, with just a few to scattered clouds in the 6-10k ft range expected through 12Z Friday.

Winds decreased slightly early this morning, but expecting winds to increase through the morning and become gusty from the NW as the sun rises and we begin to mix down higher winds from aloft. Winds will remain northwesterly this afternoon could exceed 20kt and gust to 35+kt. Winds winds begin to decrease after sunset tonight to around 10kt. After midnight, winds may shift more to the W/SW and will remain breezy between 5-10kt. There could be some low-level wind shear after midnight as well, but confidence is not currently high enough to include in the TAFs, although this will be monitored over the next several hours.

FIRE WEATHER. Westerly winds of 15 to 20 mph with gusts 30 to 40 mph today along with snow and rain showers.

Minimum relative humidity values this afternoon are expected to be in the 30s along though higher values in the 40s are expected across the western Adirondacks, western Mohawk Valley and the higher terrain of the eastern Catskills and southern Green Vermont.

Friday westerly winds of 10 to 20 mph are expected with gusts of 25 to 35 mph. Minimum relative humidity values during the afternoon are expected to be in the mid 20s to upper 30s with lowest readings in the mid-Hudson Valley.

HYDROLOGY. No widespread issues are expected on the main stem rivers through the weekend. Unseasonably cold and brisk conditions today along with some snow and rain showers. Fair weather Friday and Saturday with moderating temperatures. A widespread rainfall will occur Saturday night into Sunday.
