AREA FORECAST DISCUSSION National Weather Service Albany NY 1254 AM EST Thu Dec 12 2019

SYNOPSIS. High pressure will allow for mainly clear skies today, but temperatures will remain rather cold. Clouds will increase for Friday with moderating temperatures. The next storm system will bring periods of rain to the region for Friday night into the weekend with milder temperatures. Colder weather will return for early next week.

NEAR TERM /UNTIL 6 AM THIS MORNING/. As of 1238 AM EST . Fast moving upper level shortwave trough is now exiting to the east across northern New England. In addition to the upper level flow starting to become flatter, surface high pressure is starting to build into the area from the Ohio Valley.

IR satellite imagery, surface observations and radar imagery all show a broken band of lake effect snow extending off Lake Ontario and into our region. Some light snow showers have extended across the southern Adirondacks towards the Sacandaga and Saratoga regions, with some moisture even upsloping into southern VT as well. However, radar imagery as shown this activity become weaker over the last hour as it continue to drift southward. With high pressure building into the area, will expect this activity to shrivel up across the region, with little to no additional snow accumulation.

Otherwise, skies will be partly to mostly clear for the remainder of the overnight hours. With the high pressure area approaching, winds will start to decrease. Overnight lows look to fall into the teens for most spots.

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM FRIDAY/. Thursday, surface high pressure will move across the region which in turn will reduce and limit lake effect snow further and bring about more sunshine. As H850 temperatures will remain rather chilly from negative teens in the morning and a slight moderation in the afternoon, we will keep temperatures mainly into the 20s and some lower 30s for the mid-Hudson Valley. Some high and mid level clouds will move across the northern half of the CWA in the afternoon as mid level warm advection gets underway.

Thursday night into Friday, as the surface high becomes more removed to our east, an increasing southerly flow will become more apparent. Moisture transport at the low and mid levels increase which supports an increase in cloud coverage overnight and more so during Friday. In fact, guidance supports low level moisture transport from the eastern Gulf and western Atlantic will quickly advect northward with cloud coverage as we will increase our sky grids with this forecast package. Could even see some light precipitation evolve for our southern zones later Friday afternoon. Overnight lows range from the teens to lower 20s, and could rise overnight depending on how much cloud coverage advects across the region. Highs Friday range from near 40F for mid-Hudson Valley and southern portions of Litchfield to lower 30s across the Dacks and peaks of the southern Greens.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/. An active weather pattern is on tap through mid-December as a northern stream trough continues to be enforced across the northeast CONUS.

To begin, a strong low pressure system will take shape across the Tennessee valley into the Carolinas Friday night and track northeastward as it deepens. This will result in a wet weather weekend. Precipitation is expected to spread into the forecast area late Friday, becoming widespread by daybreak Saturday. P-type may start out as a mix of sleet or snow in the higher terrain Friday night but should eventually change over to all rain during the day Saturday. Latest GEFS ensembles show that precipitable water values reach +2 to +3 S.D. above normal so expect rain to be moderate to occasionally heavy at times. Around an inch of precipitation is possible through Saturday evening. As this system lifts into Maine, the negatively tilted trough will cross through the area as well as a surface cold front. This will allow for precipitation to continue through at least Saturday night with some locations changing back over to snow. It appears that wrap around moisture with the trough axis will result in continued snow showers through Sunday for mainly the Dacks/southern Greens/Mohawk and Schoharie Valleys. Snow showers across the high terrain will transition to lake effect snow showers for a brief period Sunday night. Highs on Saturday should reach the 40s to low 50s, with lows generally in the 30s Saturday night. Highs on Sunday will be closer to seasonable, in the low 30s to low 40s.

High pressure builds into the region for Monday with morning lows starting out in the teens to mid 20s, warming into low 20s to mid 30s by the afternoon.

The next potential weather system moves into the region Monday night with a chance for mainly snow (with a mix of rain/snow in the mid- Hudson valley) through Tuesday.

AVIATION /06Z THURSDAY THROUGH MONDAY/. High pressure will build across the area today with mainly VFR conditions. Patchy clouds east of Lake Ontario may bring SCT-BKN cloud cover at around 3000 ft along with possibly a few flurries to ALB/GFL through this morning, otherwise skies will be mainly clear into this afternoon. Coverage of any flurries will not be enough to include in the TAFs. Some mid and high clouds will spread across northern NY later today and tonight possibly bringing a period of bkn cloud cover to GFL.

Westerly winds will average 5 to 15 kts early this morning with strongest winds at ALB and weakest winds at POU. Winds will gradually turn to the south at 10 kts or less late today into tonight.

Outlook .

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

HYDROLOGY. As temperatures cool off tonight, runoff from the recent rainfall and snow melt should slow down. Any additional precipitation in the form of snow from early this morning for southern areas won't have any immediate impact on rivers and streams.

For the remainder of the work week, rivers and streams will slowly recede, although some rivers (such as the Housatonic River) may remain elevated. Another storm may bring more moderate to significant rain to the region for Friday into Saturday, which will cause rivers and streams to rise once again. Many rivers may approach bankfull levels, per the MMEFS GEFS, and some flooding will be possible, especially across western New England.

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