AREA FORECAST DISCUSSION National Weather Service Albany NY 646 PM EST Fri Nov 27 2020

SYNOPSIS. A weak cold front will trigger a few light rain showers and some light rain and snow showers overnight and Saturday morning, mainly over higher elevations north and west of the Capital District. Mainly dry, continued mild weather will prevail Saturday night and Sunday as high pressure builds across the region, then rain is expected on Monday as low pressure moves in from the south and west.

NEAR TERM /THROUGH SATURDAY/. As of 445 PM EST . Showers continue to expand in coverage just to the west of Albany. Per the H2O vapor loop, a weak short wave tracking northward just to the east of the CT River along with an area of deformation as noted in the higher moisture content seen in the imagery, should continue with these showers expanding ahead of the weak frontal boundary later tonight. So main update was to expand the PoPs/Wx a bit eastward with minor enhancements to the temps/dewpts.

Prev Disc . A series of weak short wave troughs will move across the area tonight through Saturday morning. As a result, continued cloudy weather can be expected, along with a few very light showers of rain and snow mainly north and west of the Capital District. Moisture will be rather shallow with this system and as a result precipitation type could also be in the form of some light drizzle, but again temperatures will remain generally above freezing in most areas through tonight. Lows tonight will be mainly in the 30s.

SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/. The primary short wave will pass east of our area by midday Saturday, with any lingering light showers ending by early afternoon, and some clearing possible especially in the Hudson Valley during the afternoon. Some weak cold advection will occur behind the trough, but the airmass will not be cold enough to produce any lake effect precipitation and temperatures overall will remain above normal. High pressure will build toward the region at the surface and aloft Saturday night through Sunday, bringing a period of dry, mild weather the Sunday.

The next significant storm system that will affect our area will be on Monday. Our operational models are in good agreement that phasing between the northern and southern branches of the jet stream will cause a rapid amplification of the pattern, with surface low pressure developing over the mid-Mississippi Valley and tracking toward the eastern Great Lakes on Monday. This system will spread mainly rain across our area during the day on Monday, along with increasingly gusty southeasterly winds. Other than a small chance for a little mixed precipitation on the leading edge of the system early Monday across the north country, this system appears to be almost entirely a rain maker for our area as cold high pressure will move quickly east of the Canadian maritimes and cold air damming will be limited. Earliest indications are that the heaviest rain may split around our area, with one stripe of heavy rain near the storm track over the eastern Great Lakes, while another band of heavy rain falls over eastern New England. However with this storm still 3 days away those details could still change and we will be watching this storm closely especially with regards to heavy rain potential.

LONG TERM /MONDAY THROUGH FRIDAY/. A large closed upper low will be centered over the Ohio/Tennessee Valleys Monday night. This upper low will be a bit displaced from the surface low to its northeast. This will allow for a dry slot to quickly work into the region Monday night into Tuesday morning, with the heaviest axis/surge of rain shifting into southern New England. Therefore, we may see a period of dry weather or just some drizzle on Tuesday. The two low centers phase during this period and lift northward across far western New York into southern Quebec. The wrap around moisture on the back side of the low should stay mostly out of the forecast area with perhaps the best chance for rain/snow across the southern Dacks Tuesday night-Wednesday. P-type will be primarily rain except for on the back side of the upper low. Temperatures will range from 40s to low 50s on Tuesday cooling down into the 20s and low 30s Tuesday night.

Upper ridging builds into the region with mainly dry weather through the remainder of the work week. Temperatures will be fairly seasonable and cool with highs in the mid 30s to low 40s each day. The next significant storm system takes shape for next weekend but there still too much uncertainty to talk about it yet.

AVIATION /00Z SATURDAY THROUGH WEDNESDAY/. Through 00z/Sun . A few light showers seen on the radar imagery across the region, as we will place VCSH in KGFL-KALB-KPSF. For KPOU, seems this location will remain far enough removed to not include mention in the TAF. As frontal boundary approaches overnight into early Saturday morning, while a shower or two is possible, the main impact will be from lowering CIGS to low end VFR or high end MVFR. CIGS should climb during the daylight hours on Saturday in wake of the frontal passage.

Wind will be generally out of the west at less than 5 kt tonight. Wind will increase out of the west during the midday hours Saturday at 7-14 kt.

Outlook .

Saturday Night: No Operational Impact. NO SIG WX. Sunday: No Operational Impact. NO SIG WX. Sunday Night: No Operational Impact. NO SIG WX. Monday: High Operational Impact. Definite RA. Monday Night: High Operational Impact. Definite RA. Tuesday: Moderate Operational Impact. Breezy. Chance of SHRA. Tuesday Night: Low Operational Impact Slight Chance of SHRA. SHSN. Wednesday: Low Operational Impact. Slight Chance of SHRA.

HYDROLOGY. A widespread moderate to possibly heavy rainfall Monday and Monday night. A widespread 1 to 2 inches of rainfall is possible with locally higher amounts around 3 inches especially for portions of the eastern Catskills and possibly portions of the western New England. Rainfall intensity likely won't be high enough to cause flash flooding or enough to main-stem river flooding. Still, ponding of water will be possible, especially on roadways, fields and in urban areas. Please refer to the long term section for further insight into the forecast.

For details on specific area rivers and lakes, including observed and forecast river stages and lake elevations, please visit the Advanced Hydrologic Prediction Service /AHPS/ graphs on our website.

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.
