AREA FORECAST DISCUSSION National Weather Service Albany NY 211 AM EDT Thu Aug 13 2020

SYNOPSIS. High pressure will gradually build in from eastern Canada over the next several days and will bring mainly fair weather. The exception will be the possibility for isolated storms Friday afternoon. Humidity levels will be lower, more comfortable than recently. Warm temperatures will continue with highs mainly in the upper 70s to mid 80s.

NEAR TERM /UNTIL 6 AM THIS MORNING/. As of 1:45 AM . GOES16 IR satellite shows mid and high clouds in PA and in the Southern Tier of NY spreading northeastward which should span into our region by 09 UTC - 12 UTC. While temperatureshave been falling steadily over the past few hours thanks to mainly clear skies and low dew points in the upper 50s to low 60s, the delta-T may start to slow down during the pre-dawn hours as clouds slow down radiational cooling conditions. Otherwise, our cold front remains stalled in southern CT into northern NJ where surface observations show a rather sharp dew points spread (mid 70s quickly dropping to low 60s) with southerly winds on one side of the boundary shifting to northerly winds. Water vapor imagery show a weak wave riding this boundary with KOKX showing a few showers developing in central CT in its vicinity. Therefore, we left slight chance POPs in far southern Litchfield, Ulster and Dutchess from 09 - 12 UTC to account for a brief shower.

Otherwise, expecting a cool early Thursday morning as low temperatures fall into the low to mid 50s mainly in elevation above 1500 feet and in the Mohawk Valley with low 60s elsewhere.

SHORT TERM /6 AM THIS MORNING THROUGH SATURDAY/. The Canadian high is expected to dominate our weather as the stalled boundary to our south settles farther to the south. The center of the high will drift eastward across Quebec into the weekend providing the local area with a light northerly flow and mainly dry conditions. Any threat of an isolated storms Thursday will be limited to the far southern reaches of the forecast area. There is a threat for isolated storms Friday afternoon as a weak short wave trough is expected to pass over New England with fair weather Saturday.

It will continue to be warm but with more comfortable humidity levels. Looking at highs mainly in the 80s with 70s above 2000 feet Thursday with dew points in the mid 50s to lower 60s. Friday highs are expected to be in the 80s again with 70s above 1500 feet with similar dew points. Readings Saturday are expected to be a couple degrees cooler than Friday.

LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/. A major weather pattern shift takes shape during the extended forecast period that will include a hot West U.S. vs. a mild Central/East U.S. dipole type pattern. Global forecast models continue to advertise mid-upper ridging shifting west over the western U.S. with a searing 597+ dam closed sub-tropical heat dome parked over the Southwest U.S. while resultant downstream upper troughing/broad cyclonic flow develops over the eastern two-thirds of the country.

The long-scale setup will yield a downtrend in temperatures closer to normal levels across the FA during this time frame. Our next chance for precipitation looks to come late Sunday-Monday as a surface low pressure system over the Ohio Valley/Appalachia tracks north-northeastward and phases with a eastward advancing surface cold front associated with the aforementioned upper trough extending from central Canada into the Great Lakes. Timing differences amongst forecast guidance still exists with the 12z GFS and Canadian-NH deterministic models bringing rain into the FA late Sunday-Monday and the 12z ECMWF model being the driest and slowest of the models introducing precipitation chances Monday afternoon/evening.

We're also monitoring the potential for another round of showers on Tuesday as forecast models are indicating a secondary cold front associated with the aforementioned upper trough moving over the area. Right now have kept PoPs for Tuesday at around 20% given the amount of uncertainty and strength in precipitation signals.

Wednesday, we should be rain-free with a surface high building into the region.

Daytime high temperatures will be in the upper 70s to around 80 degrees Sunday-Wednesday. Low temperatures during this time frame will be mainly in the 60s across the area (50s higher elevations). Humidity levels will be pretty comfortable with dewpoints ranging mainly in the upper 50s to low 60s.

AVIATION /06Z THURSDAY THROUGH MONDAY/. As dry air continues to move into the region, VFR conditions are anticipated through the forecast period. The only exception is the possibility of fog at KGFL early this morning, where conditions could fall to MVFR/IFR through about 12Z. For the remainder of today, expect some diurnal cu around 5-6kft and passing cirrus.

Winds will generally remain on the light side, around 5 kts or less through the period.

Outlook .

Thursday Night: No Operational Impact. NO SIG WX. Friday: No Operational Impact. NO SIG WX. 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. TSRA. Sunday Night: Moderate Operational Impact Chance of SHRA. TSRA. Monday: Moderate Operational Impact Chance of SHRA. TSRA.

FIRE WEATHER. High pressure will dominate into the weekend with mainly fair weather; the exception will be the possibility for isolated storms Friday afternoon. Humidity levels will be lower, more comfortable than recently. Warm temperatures will continue with highs mainly in the upper 70s to mid 80s.

Winds will be light. Minimum relatively humidity values will be in the 40s Thursday afternoon and in the mid 40s to lower 50s Friday afternoon.

HYDROLOGY. High pressure will dominate into the weekend with mainly fair weather; the exception will be the possibility for isolated storms Friday afternoon. Unsettled weather returns early next week.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
