AREA FORECAST DISCUSSION National Weather Service Albany NY 631 AM EDT Thu Apr 2 2020

SYNOPSIS. Cloudy and breezy conditions are expected today, with an increasing threat for some rain showers, especially across western New England. Continued cloudy and occasionally rainy weather is expected for tonight into Friday. Gradual clearing is expected early on Saturday, allowing for a milder and drier weekend with a partly to mostly cloudy sky.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 631 AM EDT . Our region continues to be influenced by a large upper level trough located over the Northeast and western Atlantic Ocean. A strong coastal storm is located well offshore of southeastern New England, but is blocked from departing due to downstream ridging.

Our region continue to see increasing clouds this morning, as both lower stratocu clouds have been increasing as well as high clouds on the backside of the coastal storm. Through the morning hours, the coastal storm will begin retrograding westward. This will allow for the clouds to continue to increase across the area. A few spots in far southern areas are still seeing some breaks, but these should be gone by about the mid to late morning hours.

With the upper level energy shifting back westward, a band of fairly steady rainfall will be moving westward across New England today. Hi-res models suggest most of the day will be dry for our area, but the precip looks to begin impacting western New England by later this afternoon into early this evening. P-type looks mainly rain, although temps aloft are fairly chilly, so if precip falls hard enough, it could be falling as wet snow for the higher terrain. This would mostly likely occur across the high terrain of southern VT above 2000 ft, as this will be the only area where surface temps may be cold enough to support the snow making it all the way to the ground. Will include a slight to low chc for some rain across eastern NY, but it looks to take until tonight for the rain to reach this far west.

Highs will be in the 40s for most areas (low 50s for the mid Hudson Valley). Some of the higher terrain of the Adirondacks and southern Greens will only reach the upper 30s for highs today.

SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/. The TROWAL precip will continue to back westward across upstate New York for tonight into Friday. Rain will continue to be fairly light in intensity, but much of the region will see some light rain, as the stacked storm system continues to sit and spin offshore New England through the entire day on Friday. Again, some wet snow could occur across the highest terrain, with the best chance of any accumulation across southern VT, where a dusting to an inch is possible across the peaks of the southern Greens.

Otherwise, cloudy, chilly and damp weather is expected for tonight into Friday for the entire area. Overnight lows tonight look to fall into the mid 30s to low 40s, with highs on Friday only in the 40s to low 50s. Highest POPs look mainly for Friday morning, as precip should start shifting back eastward for late Friday into Friday night.

Although the rain will be done, lingering low level moisture will likely keep clouds around for Friday night and perhaps even into the first part of Saturday. Lows look to fall into the 30s for most spots on Friday night. On Saturday, the return of some sunshine and building heights/temps aloft should make for a milder day. Most valley areas will reach into the 50s. Dry and quiet weather will continue for Saturday night with continued seasonable lows.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. The second half of the weekend continues to suggest an approaching cold front with clouds on the increase and the threat for some showers. However, as downstream ridge axis will remain prominent and the speed of the upstream front running into this ridge will result in a gradual decrease in shower coverage through the day. So we will hold onto 20-30% PoPs with those higher values into the Dacks. Temperatures under the increasing cloud coverage should average near to a bit above seasonable values.

Conditions should improve Sunday night into Monday as ridge of high pressure slides in from the Great Lakes region and into the northeast corridor. So under improving sky conditions, overnight lows mainly into the 30s. April sun angle, we should see highs climb Monday afternoon toward or just above 60F for valley locations with 50s elsewhere. Clouds will be on the increase yet again ahead of our next system.

A rather fast zonal and confluent flow across the northeast conus will result in less than ideal confidence of timing with upstream wave(s). First wave appears to dampen out a bit Monday night as we will continue with the 20-30% PoP grids (this time the higher value would be east of Albany with upslope conditions). A little snow is possible for the higher terrain of the Dacks and southern Greens.

Tuesday into Wednesday, a general unsettled pattern as global models differ with respect to which wave will have the most impact across the region. The 00Z ECMWF wants to take this upstream wave and track its surface reflection across the state Tuesday night with the GFS suggesting a slower pattern with the approaching warm front. The GGEM is the most aggressive with a shot of much colder air and drier conditions. So we will blend the ECMWF/GFS (along with some input from the ICON) with increasing clouds and high chance PoPs through this later period of the forecast as temperatures will likely be on the cooler side of the guidance per the aforementioned clouds and chances of precipitation. Highs mainly into the 40s for the terrain and 50s for valley locations with overnight lows generally between 35-45F.

AVIATION /12Z THURSDAY THROUGH MONDAY/. Stratus deck has expanded rather quickly with borderline VFR/MVFR ceilings. This trend will persist and likely become mostly MVFR as the afternoon progresses. Conditions worsen tonight with solid MVFR and low probabilities of IFR conditions. This will be in respect to precipitation, form of light rain, advecting in from the northeast direction and providing lower ceilings into the nighttime.

Northerly winds around 10 Kts, with a few higher gusts, becoming north to northwest through this morning at 10 to 15 Kt with some gusts over 20-28 Kts. The gust factor should subside toward or shortly after sunset but sustained magnitudes at or above 10kts expected.

Outlook .

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

FIRE WEATHER. Increasing clouds are expected through the day today. RH values will only be as low as 45 to 60 percent and some rain will arrive by late today into tonight. Widespread clouds and rain is expected tonight into Friday. Clearing will finally occur by Saturday. Total rainfall will range from a few hundredths over western areas to nearly one half inch across southern Vermont.

Northwest winds of 10 to 20 mph are expected today and some gusts will exceed 25 mph at times. Northerly winds will continue to be around 10 mph for tonight into Friday. Lighter winds are expected over the weekend.

HYDROLOGY. Rain associated with a sprawling coastal storm will back into the region later today and continue for tonight into Friday. Total rainfall amounts will only range from a few hundredths over far western areas to nearly one half inch across southern Vermont. This rainfall won't have much impact on rivers and streams across the region.

With the strong coastal storm sitting offshore, tidal impacts are anticipated along the Hudson River and lower reaches of its tributaries across the mid Hudson Valley. During the time of high tide, the river may come close to flood stage for late Friday into Saturday.

Dry weather is expected for the weekend into early next week. The next chance of widespread rain appears to be Tuesday night into Wednesday at this time.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
