AREA FORECAST DISCUSSION National Weather Service Albany NY 136 PM EDT Tue Mar 31 2020

SYNOPSIS. A rather unsettled pattern will continue as we remain under the influence of an upper level low pressure system. While somewhat drier air will filter into the region this afternoon through Wednesday, more moisture returns for Thursday with an increasing chance for wet weather. Conditions will improve toward the weekend with a return toward seasonable temperatures.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 1240 PM EDT, earlier breaks in the clouds have filled in, as convective temps have been attained in combination with considerable low level moisture remaining below inversion. Still some sprinkles/patchy drizzle across the southeast Catskills, and this may persist through mid afternoon.

Otherwise, deeper layer of dry air continues to slowly settle south and west across far northern New England/NYS. This may allow for greater breaks in the clouds to develop later this afternoon or closer to sunset across portions of the upper Hudson Valley and southern VT, perhaps even portions of the southern Adirondacks.

Afternoon highs should climb into the mid-upper 40s for valley locations and upper 30s to lower 40s for the highest terrain areas.

SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/. As seen in the H2O vapor imagery, an impressive upper wave was transversing along or just south of I70 corridor. This wave is expected to track off the mid-Atlantic coastline tonight as main upper low remains across the northeast corridor. 00Z model trends are toward a rapidly intensifying coastal storm overnight and well southeast of the region. Its residual impact to our local area would be a region of increased subsidence as mid levels continue to dry out from northeast to southwest. So we will adjust sky coverage a bit toward a partly cloudy sky for most areas (exception to this will be into the Catskills with a persistent north-northeast low level trajectories). Overnight lows will be on the chilly side with 20s for the terrain and lower 30s for the Capital Region and points southward through the Hudson River Valley.

Wednesday, the upper low remains across the region as rapidly deepening coastal storm continues to evolve. So some additional subsidence is expected as we will continue with the partly sunny forecast, on average. Highs should be able to recover toward 50F for valley locations and mostly 40s elsewhere.

Wednesday night into Thursday, this coastal storm will become vertically stacked and result in moisture wrapping around and returning from the north-northeast. So a mainly dry Wednesday night with an increase in cloud coverage to the north and northeast of Albany with lows generally falling between 25-35F. Those clouds continue to advect in and lower with increasing chances for light precipitation developing. The higher PoPs will be to northeast of Albany with slight chance values to the west and southwest of Albany. Some light snow will be possible around 2k feet per wet bulb zero height forecasts. Under the increase clouds and probabilities of precipitation, temperatures will be a touch cooler than Wednesday's highs.

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/. Large closed off upper level low will continue to be located just off the coast of New England for Thursday night. An additional upper level disturbance will be rotating westward around the northern side of this feature for Thursday night, allowing for plenty of clouds and some additional showers across our area. Best chance will be across northern and eastern areas. Any precip looks fairly light. P-type should be mainly rain, although can't rule out some wet snow mixing in at the highest elevations, as lows should be in the mid to upper 30s.

By Friday, the upper level low will be starting to slide eastward and some ridging will start to build into the region. This should allow the clouds to gradually break up across the area. Still could be a rogue shower around early in the day (especially for western New England), otherwise, dry weather looks to return. With the return of sunshine and rising height, temps look to reach into the 50s for valley areas.

Over the weekend, high pressure should allow for mostly dry weather, but a weak frontal boundary will be moving across the region towards the end of the weekend for late Sunday. This northern stream feature looks fairly weak and won't have a lot of moisture, but can't rule out a shower with it. With some sun expected, high temps look to reach well into the 50s each day, with overnight lows in the 30s. Models suggest even higher heights/warm temps aloft should build in for Monday, so temps may be even warmer to start early next week.

AVIATION /18Z TUESDAY THROUGH SUNDAY/. As of 18z, low-level stratocumulus clouds continue across all TAF sites with ceilings still MVFR but inching closer to VFR range. With drier air continuing to build in, expect ceilings to gradually move into the low-VFR range this afternoon and continue through much of the overnight. There is uncertainty as to if MVFR ceilings due to a lowering cloud deck and/or patchy fog return later tonight (best chance would be at KPOU). For now, will maintain VFR conditions with this update. Subsidence builds across the region tomorrow morning with a mostly clear sky in store, especially from late-morning on.

Wind will be variable at 5 kt or less across all sites through tonight (with occasional 10 kt wind at KGFL this afternoon). Wind will then be out of the north at 6-12 kt tomorrow.

Outlook .

Tuesday Night: Low Operational Impact. NO SIG WX. Wednesday: No Operational Impact. NO SIG WX. Wednesday Night: No Operational Impact. NO SIG WX. Thursday: Low Operational Impact. Slight Chance of SHRA. Thursday Night to Saturday: Low Operational Impact. NO SIG WX.

FIRE WEATHER. An upper level low will continue to bring unsettled conditions. More clouds than sunshine are expected today, but areal coverage of showers should decrease as the low weakens. Temperatures will remain a little cooler than normal as we close out the month of March and enter April.

The RH values will only lower to 55 to 70 percent this afternoon and rise at or above 80 percent tonight.

The winds will generally be light and vary in direction at less than 10 mph.

HYDROLOGY. No widespread flooding is expected in the ALY HSA over the next several days.

Little in the way of precipitation is expected through Thursday morning. Spotty light rain or showers will redevelop late Thursday afternoon through Friday morning, with amounts generally remaining under one quarter of an inch (with greatest amounts for areas east of the Hudson River, as well as the northeast Catskills.)

Latest river observations and NERFC forecasts indicate river levels remaining below action stage, although some may crest just under action stage across the upper Hudson Valley (i.e., Hadley/Hudson R) this afternoon. Slower responding Riverbank may also approach action stage tonight into Wednesday. Otherwise, river levels should generally slowly recede later this week.

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.
