AREA FORECAST DISCUSSION National Weather Service Albany NY 1249 PM EST Sun Mar 7 2021

SYNOPSIS. High pressure will ridge in today with some sunshine, and continued colder than normal temperatures to close the weekend. The surface high will continue fair and cold weather to open the week, but a weak disturbance and a warm front will increase clouds and bring some scattered snow showers and flurries Monday night. A warming trend persists Tuesday through the mid week with temperatures rising well above normal for March.

NEAR TERM /THROUGH TONIGHT/. Early afternoon water vapor imagery shows the cold upper trough lingering over the Northeast, providing chilly temps despite full sunshine across the forecast area. Height rises are working their way into the Northeast from the west, which is resulting in high pressure at the surface building over western New York/the eastern Great Lakes. Lake clouds are well west of the forecast area, but still potential for some sct stratocu to develop the remainder of the day. Highs are coming up 5-10F short of normal despite the strong insolation.

Tonight, the surface high builds eastward, which should lead to good radiational cooling conditions, especially west of the Hudson where it is closer to the high and there is still snowpack. Cut back on overnight lows here, which should fall to 0 to -10F over the southern Adirondacks with mainly 0-15F elsewhere.

SHORT TERM /MONDAY THROUGH TUESDAY/. Monday . Another fair day is expected with the sfc anticyclone near the East Coast and heights continue to rise ahead of a weak sfc cyclone approaching from the upper Great Lakes Region and Ontario. In the low to mid level warm advection pattern H850 temps warm to -1C to -5C during the day based on the GFS/NAM.

Some mid and high clouds increase from the west/northwest during day. Temps slowly trek upward with upper 20s to mid 30s over the higher terrain and mid 30s to around 40F in the valley locations and across the hills

Monday Night . The warm front tied to the weak disturbance moving across southeast Canada in the west to northwest flow aloft will bring some isolated to scattered snow showers and flurries. The depth of the low level moisture looks scant and the synoptic forcing is not strong. The NAM/QPF paint some very light QPF across the region. There could be some coatings to few tenths of an inch of snow over the higher terrain and north of ALY. Temps may tail off early in the evening into the upper teens and 20s and then rise some overnight.

Tuesday . A weak cold front slides through in the morning with limited cold advection. The sfc winds will shift to the west northwest, and then the uptick of temps begins. We could see the warmest temps of 2021 in some locations with downsloping off the eastern Catskills, Helderbergs and eastern Adirondacks combined with deeper mixing close to H850. The temps at H850 will be in the -1C to +2C range based on the 00Z/GFS late in the day. Partly to mostly sunny skies are expected with max temps in the upper 40s to lower and spotty mid 50s (closer to KPOU) in the valleys, and upper 30s to mid 40s over the mtns. KALB has not hit 50F this year and we could be close to that number on TUE.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. The extended forecast period will feature Spring-like temperatures to start the period Wednesday and Thursday before turning colder late week and during the weekend. The long-term period starts off dry, but precipitation chances increase Thursday and Friday due to an approaching cold front.

We start off the period Tuesday night with an anomalously strong H500 ridge over the eastern CONUS. At the surface, a strong 1032 mb high pressure system will be sliding to our east. Winds will turn out of the south-southwest with a warm front lifting over the area during the day on Wednesday. This will effectively put the area in the warm sector of a storm system to our west and allow for increase temperature and moisture advection to take place. High temperatures will climb into the 60s along the Hudson Valley Wednesday and Thursday. Clouds will be on the increase Wednesday night Thursday as the cold front nears. Wednesday night into Thursday, precipitation will increase in coverage from northwest to southeast. Given the warm airmass in place, precipitation will be in the form of rain. The bulk of the rain will be confined to areas northwest of the Hudson Valley (Wednesday night into Thursday). Rain looks to eventually get into the rest of the area Thursday night into Friday. This is where we have our highest confidence of more widespread rainfall including the Capital District (Thursday night into Friday). Sometime during Friday afternoon hours, things look to dry out from west to east. With the cold fropa, a cooler airmass will take place over the weekend.

Forecast models namely the EC/CMC are indicating a shortwave/surface storm system ejecting out of southeastern Canada. Should this verify, we could get some additional precipitation in the form of snow showers in the Sunday to Monday timeframe.

As touched on earlier, temperatures are forecast to be Spring-like during the beginning parts of the long-term period. Daytime highs Wednesday and Thursday will climb into the 50s and 60s with the warmest temperatures located along the Hudson Valley from Albany and points south. Temperatures will then fall Friday through Sunday due to the aforementioned cold front. Daytime high temperatures Friday will be in the 40s and 50s, Saturday 30s and 40s, and mostly 30s on Sunday. Nighttime low temperatures will be in the 20s to near 30 Tuesday night into Wednesday morning, 30s and 40s Wednesday and Thursday nights, 20s and 30s Friday night, and mostly 20s Saturday and Sunday nights. Overall, anomalies will run warmer than average during this time period.

AVIATION /18Z SUNDAY THROUGH FRIDAY/. Through 12z Monday .

VFR conditions are expected to persist through the 12z TAF cycle. Expect a mostly sunny day with just a few high cirrus clouds as a 1028+ mb surface high pressure system builds into the region.

Winds will be light out of the northwest at 5-10 kts through the 12z TAF cycle.

Outlook .

Monday Night: Low Operational Impact. Slight Chance of SHSN. Tuesday to Wed night: No Operational Impact. NO SIG WX. Thursday: Low Operational Impact. Slight Chance of RA.

HYDROLOGY. No widespread hydrological issues are expected through the mid to latter portion of next week.

Cold and mainly dry weather will persist today into Monday with little impact on the waterways. Any decrease in snowpack will be through sublimation. A weak disturbance and a warm front will bring a few hundredths of QPF to a few spots Monday night.

Tuesday through the mid week temperatures will moderate above normal with some snow melt. The next chance of widespread showers may not occur until late Thu into Fri. Total QPF does not look very heavy with the frontal passage late in the week with a tenth to a quarter inch perhaps across northern basins. Some ripening of the dense snow pack is possible over the northern mountains. Some river and streams may show a diurnal fluctuation in flows/hydro traces with snow melt through the mid to end of the week. However, widespread ice break-up or hydro issues are not anticipated at this time on the rivers/streams.
