Area Forecast Discussion National Weather Service Buffalo NY 1100 AM EDT Thu Jul 16 2020

SYNOPSIS. A series of weak fronts will support scattered strong to severe thunderstorms from midday today into this evening. Mid summer heat and humidity can then be expected for Friday through at least the weekend.

NEAR TERM /THROUGH TONIGHT/. . Strong to severe thunderstorms this afternoon and evening..

Well defined MCV spinning eastward over western Lake Erie will make its way across western New York this afternoon and to north of the North Country this evening. This feature will push a series of weak fronts across our region today. Initial showers and storms during the midday not expected to be significant . but as the activity moves east it could intensify over parts of the Genesee valley. Of greater concern will be convection that will blossom this afternoon in the wake of the initial area of showers and storms.

Greatest risk for strong to severe storms still likely in time range from mid afternoon into early this evening. Strong winds aloft tied to the MCV results in effective shear over 40 kts which is strong for middle of summer with low-level shear 25-30+kts also strong. The shear combined with seasonable instability (highs in the mid 80s with dewpoints in the mid 60s) with MLCAPES 1000-1500j/kg and DCAPES to around 1000j/kg sets the stage for storms with damaging winds the primary threat, but not the only threat. Within slight risk over WNY, SPC probs have WNY in a 5 pct risk for tornado (increased from ydy) which is pretty rare for our severe weather season. Looking at parameters specific to forecasting tornado potential (STP, LCL, effective helicity) we are looking to be on the high end for past tornado days in WNY. Continue to mention this risk in the HWO. It certainly looks justified. Best potential will be mid to late afternoon as storms will initially be discrete with possible supercells. Eventually though given the strong 0-1km shear and the approaching front, storms should become linear as they move east toward Genesee valley and perhaps western Finger Lakes/SE Lake Ontario region with gusty to damaging winds the prime threat. Finally, torrential downpours will be likely in any storm as PWATS surge to over 2 inches. Storms will be moving, so would likely need to have training storms for larger flooding risk.

Expect clusters of diminishing thunderstorms to rumble toward the North County early in the evening while diminishing over WNY and Genesee valley. Showers will diminish further overnight as cool and moist air works in behind the front. Based on upstream trends behind the low this morning, could see low stratus and fog later tonight with dense fog possible in typically prone valleys of the Southern Tier. Lows tonight in the mid 60s to around 70F.

SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/. Cold front will slowly press from west to east across the forecast area on Friday, pushing east of the region by mid afternoon. This will allow any leftover showers (and storms east of Lake Ontario) to taper off in a similar fashion. Weak upper level ridging and surface high pressure will then be the dominate features for Friday night through Saturday night providing dry weather. Otherwise, high temperatures on Friday will be mainly in the low to mid 80s. Warm advection will be on the increase by Saturday. This will boost highs into the mid and upper 80s across much of the forecast area, with the typically warmer locales across the Genesee Valley and lake plains south of Lake Ontario likely reaching the lower 90s. Humidity levels will remain in check, which should preclude the need for any heat related headlines, as apparent temperatures should fail to reach 95F anywhere in our forecast area.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. Sunday will be the warmest day of the period, along with a marked increase in humidity levels as well. The first half of the day should remain dry, before the chance for a few showers and storms increases from northwest to southeast across the area later in the afternoon into the evening well ahead of an approaching cold frontal boundary. However, the main story will be the heat and increased humidity for the second half of the weekend. 850Ts in the vicinity of +20C will allow high temperatures to surge into low to mid 90s across much of the lower terrain south of Lake Ontario, with upper 80s elsewhere. The combination of these temps and dew points rising into the upper 60s to low 70s will possibly necessitate the need for heat headlines across the lake plains, Genesee Valley and Finger Lakes region.

A better chance for showers and storms comes Sunday night as a weak cold front crosses the region. Our area will then become sandwiched in between strong upper level ridging to the south and broad upper level troughing across the upper Great Lakes and southeastern Canada. Mid level flow will strengthen in response to this regime, however there are no pronounced disturbances set to move through the upper flow during this time. This should translate to a good deal of dry time, however the combination of continued heat and humidity along with enhanced upper flow may be enough to produce a few showers or storms from time to time, especially during the afternoon and early evening. A sharper upper trough and associated surface wave will approach the area Wednesday, bringing a better chance for some showers and storms as we approach mid week. Otherwise as mentioned, the heat and humidity will stick around through the first half of next week. However, it will not be nearly as warm as Sunday, with highs generally ranging from the lower to mid 80s Monday through Wednesday.

AVIATION /15Z THURSDAY THROUGH MONDAY/. While VFR conditions will be in place across the region for the bulk of this afternoon . showers and thunderstorms will become increasingly widespread. This will result in localized MVFR conditons with some of the stronger storms producing very heavy rain and localized wind gusts over 40 kts.

In the wake of the convection . tonight will feature IFR to MVFR cigs. The stronger storms will taper off to scattered showers from west to east.

Outlook .

Friday . Becoming VFR. A chance of showers in the morning. Saturday . VFR. Sunday and Monday . Mainly VFR. A chance of showers and thunderstorms.

MARINE. Winds will veer to the south across the region today, and while winds will freshen a bit in some areas, the main concern will be the likelihood for thunderstorms this afternoon and evening. The storms will have an elevated risk of producing strong wind gusts.

A brief period of stronger winds are expected tonight. Though southerly wind direction will be mainly offshore, wind speeds and waves support Small Craft Advisory over nearshore waters of far eastern Lake Ontario.

BUF WATCHES/WARNINGS/ADVISORIES. NY . None. MARINE . Small Craft Advisory from 11 PM this evening to 8 AM EDT Friday for LOZ045.
