AREA FORECAST DISCUSSION National Weather Service Albany NY 517 AM EDT Tue Sep 22 2020

SYNOPSIS. High pressure will drift east and south of our region and control the weather for the upcoming week with dry and mainly sunny weather. Temperatures will steadily climb with temperatures warming to above normal into the weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Clear sky other than some haze/smoke well aloft. Tropical system tracking east of the region will tighten the pressure gradient across our area. Winds will become gusty by afternoon, especially from the Hudson Valley through western New England. Gusty winds continue through the afternoon. See fire weather section for details on the Red Flag Warning in effect today for the Berkshires.

Flat upper ridging building in from the west will allow boundary temperatures to warm slowly. So, with the sunshine, gusty winds and decent mixing, highs in the mid 60s to near 70 but lower 60s in higher terrain.

SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY NIGHT/. Winds should diminish to light through the evening but slow and gradual warm advection with the low level ridging building east and flat upper ridging building in, temperatures should fall to the 40s to around 50, so no frosts or freezes. A weak wind shift boundary tracks through toward morning but other than some haze/smoke aloft, there should be lots of sun and becoming breezy again. Highs Wednesday in the lower to mid 70s but mid to upper 60s higher terrain.

Continued gradual warming Thursday with another weak wind shift boundary approaching from the north late Thursday afternoon and night that may not make it to our area because it is so weak. Southern stream upper energy and moisture is expected to track well south while weak northern stream energy with very little moisture associated is expected to track near or just north of our region. Some clouds and an isolated shower are not out of the question north of the Mohawk Valley late Thursday afternoon and evening. Not including any showers, though, due to the weak upper energy, no organized low level forcing and very little deep moisture. Highs Thursday in the 70s with upper 60s higher terrain.

LONG TERM /FRIDAY THROUGH MONDAY/. Our stretch of dry and warm weather continues through the first half of the weekend before an amplifying trough from the Central Plains progresses eastward and provides the Northeast with multiple chances for precipitation to the start the new work week. Read on for details.

Our weak and moisture starved cold front from Thursday looks to be settled across the North Country on Friday. As upper level ridging builds into the Northeast, this boundary lifts northward and southwesterly return flow develops. Warm air advection should allow 850mb isotherms to climb to +11C to +13C which should result in high temperatures warming into the mid to upper 70s with even near 80F possible in the mid-Hudson Valley. By late September standards, this is about 10 degrees above normal and with dew points rising back into the upper 50s, it will feel more like summer again. Despite warm air advection in place, subsidence overhead should keep skies mainly sunny once again.

High pressure centered over the western Atlantic strengthens Friday night with southeasterly flow ensuing in response over eastern NY and western New England. This should advect in a marine influenced air mass which may result in increased clouds Friday night, especially over the mid-Hudson Valley and NW CT. We left skies mainly clear for now since timing marine stratocumulus clouds is difficult this far in advance. While high pressure off shore continues to strength into Saturday, southerly flow looks to direct the remnant moisture from what was once Tropical Cyclone Beta across the mid- Atlantic and perhaps southern New England. Should it scrape our southern zones, this would mainly result in increased cloud coverage with perhaps a few light over the mid- Hudson Valley and NW CT. The remainder of the region should remain mostly sunny as upper level ridging continues to build over the eastern seaboard. South- southeasterly flow on the western side of the high should keep temperatures warm but could fall a few degrees cooler than Friday given the marine influenced air mass advecting inland.

Upstream, we will closely monitoring a longwave trough progressing eastward across the Great Lakes. While the amplification of this trough has backed off compared to previous model runs, it has Pacific origins and thus should carry sufficient moisture with it, even this far east. Off shore high pressure stays dominant heading into the first half of Sunday but as southwesterly flow increases and heights quickly fall in response to the approaching trough, we increased POPs Sunday afternoon into Sunday night from southwest to northeast. Since signals in the guidance suggest the trough may become neutrally to even potentially negatively tilted, the associated surface cold front could be rather potent and lead to a more organized area of rain late Sunday afternoon or Sunday night. With strong southwesterly flow advecting in moisture from the Gulf of Mexico, it will feel humid with PWATs rising towards 1.50". Thus, there may even be a few rumbles of thunder as the possibly strong boundary passes through. We left out thunderstorms at this point but depending on trends, we may introduced it in future forecasts.

Unsettled conditions continue Monday and Tuesday as strong ridging (H500 heights +590dm) in the west-central Atlantic keep the pattern amplified (H500 heights 2 to 3 standard deviations below normal across the Great Lakes/Midwest) allowing additional shortwaves within the broader longwave trough to impact our region. We kept chance POPs in the forecast for both days. Increased cloud coverage and chances for rain plus westerly winds advecting in cooler air should result in lower high temperatures than previous days. Highs should trend back towards normal levels for late September, falling back into the mid-upper 60s. Overnight lows, however, should stay mild due to increased cloud coverage.

AVIATION /09Z TUESDAY THROUGH SATURDAY/. Radiational cooling is underway tonight with temperatures slowly approaching their respective dew points which has resulted in MVFR visibilities at GFL. ALB, PSF and POU still remain VFR but the observers at ALB have already indicated BCFG which makes sense given that the dew point and temperature are now equal. As clear skies and calm winds continue for the remainder of the night, we will be monitoring GOES16 satellite night fog channel for indications that fog is becoming more widespread and thicker. Latest guidance suggests the main window for potential MFR visibilities at PSF and POU and even IFR visibility at ALB and GFL looks to be 09-12 UTC/Tue.

Any patchy ground fog should lift by 12-13UTC/Tue with VFR conditions following for remainder of the TAF cycle.

Calm winds tonight will become breezy towards 15 UTC with sustained winds from the north-northwest ranging 8-12kts with gusts 15-20kts during the afternoon. Wind gusts subside by sunset by sustained winds likely remain near 5-8kts overnight. Low-level wind shear is be possible at POU towards the end of the TAF period but due to uncertainty, we did not include this in the latest TAF issuance.

FIRE WEATHER. Red Flag Warning for Berkshire County 9 am this morning through 9 pm this evening due to low RH and gusty winds .

High pressure will drift east and south of our region and control the weather for the upcoming week with dry and mainly sunny weather. Temperatures will steadily climb with temperatures warming to above normal into the weekend.

RH values are expected to fall today to 30 to 40 percent in the afternoon, with northwest winds increasing 10 to 15 mph. Western New England and some parts of eastern NY could see gusts up to 25 mph Tuesday afternoon. Southern VT, NW CT and the mid Hudson Valley in eastern NY could see gusts to 20 mph.

RH values will rise back to the 70 to 100 percent range tonight with northwest winds diminishing to less than 15 mph and shifting to west. RH values drop to the 35 to 50 percent range Thursday afternoon with winds shifting back to northwest at around 15 mph. The next chance for rain will not be until early next week.

HYDROLOGY. High pressure will be in control through much of this week, allowing for mainly clear skies and no precipitation. With no storms systems heading our way, dry weather is anticipated to continue through much of the upcoming week as well. This will allow for river and stream levels to hold steady or slowly fall. Many locations are already seeing below normal stream flows and this is expected to continue. The next chance for rain will not be until late next weekend.
