AREA FORECAST DISCUSSION National Weather Service Albany NY 1011 PM EDT Mon Sep 21 2020

SYNOPSIS. High pressure will control the weather for the upcoming week. Temperatures will steadily climb with anomalies getting back to warmer than normal levels later in the week. Dry and mainly clear weather is expected to continue.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. As of 1015 PM EDT, skies remain clear (other than the haze aloft) as temps settle back through the 40s and mid/upper 30s.

Things will remain quiescent for the rest of this evening and tonight with the surface high parked overhead. Clear skies and light winds tonight will result in plenty of radiational cooling to take place which will allow for temperatures to approach there dewpoint/crossover temperature values which ultimately could result in the development of some patchy fog. This is especially true across the river valley areas as air flow descends from the higher elevations helping to lower temperatures even further. Additionally, patchy areas of frost could develop over areas in which the growing season hasn't ended with overnight low temperatures progged to fall into the low to mid 30s. A Frost Advisory has been issued from 4am to 8am EDT Tuesday for Litchfield, eastern Schenectady, southern Saratoga, eastern Albany, western Rensselaer, eastern Greene, Columbia, eastern Ulster, and Dutchess counties.

SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/. Weather highlights through the short term period will focus on 1) an elevated risk for fire Tuesday afternoon (western New England), 2) increased concentration of smoke aloft affecting our skies, and 3) the potential for some increased cloud cover on Thursday in response to a northern stream upper impulse to our west.

Tuesday-Wednesday

For Tuesday, high pressure will remain over the area yielding to another tranquil day with plenty of sunshine. Winds will be on the increase however Tuesday afternoon as the pressure gradient tightens over the area with the FA being sandwiched in between the aforementioned surface high and Tropical Storm Teddy which will be passing well to our east over the Atlantic Ocean. See www.hurricanes.gov for more information regarding Tropical Storm Teddy. Tuesday afternoon, winds will increase 5 to 15 mph out of the northwest with gust as high as 25 mph especially across the Catskills, the Berkshires, and western New England. Given that RH values will be ranging from 30 to 40 percent, have issued a Fire Weather Watch for the Berkshires through Tuesday evening for the risk of fire. Wednesday will feature another quiet day with high pressure still in control. Gusty northwest winds will continue through the day with gusts up to 20 mph.

Thursday

Thursday will be another tranquil day, but clouds could be on the increase during the afternoon/evening hours as mid to upper impulses approach from the west.

With the H500 pattern expected to flatten and become a bit more zonal, smoke from the western U.S. wildfires will affect our skies giving way to a hazy look at times Tuesday, Wednesday, and possibly into Thursday. Given the fact that the smoke is well up above the surface, we do not anticipate this having any public health impacts.

Temperatures will steadily be on the increase through Thursday with anomalies going from cooler than normal values to warmer than normal values. Daytime temperatures are progged to approach the mid 60s on Tuesday, low 70s on Wednesday, and the low to mid 70s on Thursday across the valleys (cooler higher elevations). Overnight lows will be in the range from the upper 20s to upper 30s tonight, 40s Tuesday night (low 50s mid-Hudson Valley), and low 50s Wednesday night.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. Dry conditions with warm temperatures running about 5-10 degrees above normal temperatures will continue through the end of the work week before a longwave trough from the western CONUS amplifies as it digs into the Great Plains. The deterministic global guidance has captured this longwave trough over the past few models runs.1 Although there remains uncertainties regarding its timing, intensity and placement among the GFS, ECWMF and CMC solutions, this feature represents a pattern shift from persistently dry conditions to one with increasing chance for rain. Read on for details.

Zonal flow ensues Thursday and Friday over eastern NY/western New England as our region is caught within a split flow regime. While a weak shortwave passes well to our north, broad ridging settles over the Southeast U.S. A weak cold front associated with the northern stream shortwave may brush our northern zones on Thursday but this feature is moisture starved so we continued a mainly dry forecast, outside of slight chance POPs in far northern Herkimer and Hamilton counties. Westerly flow becomes southwesterly on Friday as the aforementioned cold front lifts northward as a warn front front and ridging within the southern stream builds northward. With 850mb isotherms ranging +9C to +12C both days, high temperatures should reach into the mid to even upper 70s in valley areas (perhaps near 80 in the mid-Hudson Valley) with upper 60s to low 70s in the higher terrain. The one fly in the ointment could be the effect any smoke from the wildfires in the western U.S has on our temperatures, should smoke still be overhead for the end of the week. Overnight lows should remain mild, only falling into the 50s (upper 40s in terrain areas).

By Saturday, ridging over the western Atlantic strengthens in response to our longwave trough digging over the Central Plains. As a result, the associated surface high pressure that now shifts into the northern Atlantic looks to build to ~1030mb and maintain dominance over the eastern seaboard on Saturday. Given that the high is centered so far out to sea, the clockwise circulation around it should cause winds to back to the southeast. This would advect in marine influenced air mass and thus introduce higher humidity and slightly cooler temperatures compared to previous days but still remain above normal.

Sunday and Monday feature increasing chances for precipitation as the longwave trough in the Great Plains progresses eastward and strong southwesterly flow ahead of it pushes into the Northeast. As warm air advection increases and directs moisture from the Gulf of Mexico towards our region, PWAT values should rise as well. The ECWMF seems to be handling this trough the best of the deterministic guidance as the GFS and CMC suggest the amplifying trough quickly becomes a cut off low but this seems too progressive. To capture the advancing trough and increasing moisture advection, we introduced slight chance POPs for the entire area on Sunday and increase to chance POPs Sunday night into Monday. Depending on how this potentially amplified longwave trough evolves, there could be a multi-day period with chances for much needed precipitation before we close the weather books on September.

AVIATION /02Z TUESDAY THROUGH SATURDAY/. High pressure will remain anchored across the region through Tuesday.

VFR conditions are expected through this evening. Thereafter, some patchy ground fog may develop at KGFL/KPSF and KALB, with best chances during a brief window between 10Z-13Z/Tue. During this time, periods of MVFR/IFR conditions could occur. At this time, due to uncertainty, have only suggested shallow/patchy fog at these terminals during the 10Z-13Z/Tue window.

Any patchy ground fog should lift by 13Z/Tue, with VFR conditions then expected through the day.

Light/variable winds should trend to calm overnight, then increase from the north to northwest Tuesday morning to 8-12 KT, with some gusts of 15-20 KT possible during the afternoon.

FIRE WEATHER. Fire Weather Watch for Berkshire County Tuesday morning through Tuesday evening due to low RH and gusty winds .

Low relative humidity levels coupled with gusty winds has resulted in the issuance of a Fire Weather Watch for the Berkshires for Tuesday.

High pressure will control the weather during the upcoming week. Temperatures will moderate back to above normal, with dry and mainly clear weather expected to continue.

RH values will rise tonight to near 90 percent. RH values are expected to fall Tuesday to 30 to 40 percent in the afternoon, with northwest winds increasing 10 to 15 mph. Western New England could see gusts up to 25 mph Tuesday afternoon. 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.
