Area Discussion for - Binghamton, NY
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kbgm 192044 afdbgm area forecast discussion national weather service binghamton ny 444 pm edt Fri jul 19 2019 Synopsis A hot and humid airmass continues today and Saturday across the region with dangerous heat index values. Most of the area will see a chance of thunderstorms through the weekend as several disturbances pass through. Conditions will remain quite warm and humid Sunday although not as hot, with cooler air expected Monday onward. Near term through Saturday night 445 pm update... Updated pop based on latest radar and mesomodels trends. Thunderstorms will be pushing across central ny and the twin tiers region this evening... With strong gusty winds and torrential rainfall. Flash flooding remains a concern due to the intense rainfall rates and slow moving training storms. Damaging winds also remains the main threat, especially across the twin tiers as we head into the evening hours. 330 pm update... a severe thunderstorms watch is in effect for all of central ny and portions of NE pa until 10 pm this evening. Main concerns in the near term remain focused on the scattered thunderstorms... Some possibly severe... Expected to develop and move in from the west this afternoon and evening along and ahead of an advancing mesoscale convective system... And also the continued threat of very hot and humid conditions today and Saturday. There is also the potential for some afternoon evening convection Saturday, but the threat for severe weather appears limited. A broad, large dome of high pressure continues to build newd into the ERN great lakes and northeast today with temperatures climbing into the upper 80s and lower 90s, with dew points in the mid to upper 70s making it feel like upper 90s to around 110 deg. An excessive heat warning remains in effect through tomorrow with the very warm and humid air mass remaining in place into the weekend. Conditions tomorrow will be slightly warmer with heat index values above 105 deg for a number of locations... Especially the populated valley locations and across the lake plain south of lake ontario. The amount of heat and humidity this afternoon has allowed the atmosphere to become very unstable with ml CAPE values above 3000 j kg. A very persistent MCV that rolled across SRN ontario earlier today has maintained strength moving east along a fairly strong stability gradient... And is now starting to tap directly into the unstable boundary layer into far WRN ny as a strong line of convection. However, out ahead of the convective system a broad area of scattered convection has formed with not very much organization to the individual cells. A lack of shear and steering flow should allow the lead convection to persist, but have a hard time becoming severe. The arrival of the mcv, or what's left of it, later this evening may have enough storm induced shear to ramp the convective intensity back up again. The main threat will likely be damaging winds, but some large hail cannot completely be ruled out. The threat for heavy rain may tick up again this evening as soundings become favorable for heavy downpours. Slow-moving storm cells and plenty of moisture... Pwats 2-2.5 inches... With tall skinny CAPE profiles could lead to a threat of localized flash flooding. Some areas may see rainfall rates 1-2 inches per hour. Wpc has upgraded portions of the finger lakes and the central SRN tier to a slight risk for excessive rainfall. |
The MCV should dissipate close to or just after midnight as it tracks to the south and SE into NE pa. Weather conditions should become relatively quiet late tonight and into Saturday morning, but with another round of showers and storms filling back in by the late morning, and even more so by the afternoon as the boundary layer destabilizes. Shear remains weak, but with an abundance of deep moisture and a strong amt of sfc based cape, the possibility of scattered thunderstorms returns. The fact that there is no MCV or primary forcing mechanism should limit the threat for severe weather. Short term Sunday through Sunday night 230 pm update... a cold front pushes through the region from NW to SE on Sunday. However, heat index values will still come close to excessive heat criteria across at least the southern half of the forecast area depending on the timing of the front. Slightly cooler air works its way into the region behind the front Sunday night, with overnight lows dipping into the low to mid 60s with the only exception being NE pa, where lows may still be in the upper 60s to low 70s. Long term Monday through Friday 230 pm update... The biggest change to the forecast will be due to model guidance now in good agreement of another front upper trough pushing through the region Monday into Tuesday, so have increased pop this period. High pressure will then push in behind this next system and a cool dry airmass should persist through the remainder of the period. Aviation 21z Friday through Wednesday A very unstable air mass is developing this afternoon which when combined with an incoming convective complex over SRN ontario, will eventually lead to scattered thunderstorms... Generally between 22-04z across the ny terminals. Confidence is still not high enough to include TS in the kavp forecast at this time. Later tonight after the thunderstorms, may see a brief period of MVFR cigs and or vsbys due to low clouds and fog where rain develops today... But with conditions returning toVFR after 14z sat morning. Will likely be updating tafs for timing as the TS approach the area later today. Expect SW winds 5-10 knots during the day with erratic gusts near any storm cells. Outlook... Saturday through Saturday night... Weak passing disturbances will chances for showers and storms yet it will beVFR most of the time. Sunday through midday Monday... Better chances for scattered showers and thunderstorms and associated restrictions as a frontal boundary slowly moves through the region. Late Monday through Wednesday... MainlyVFR other than potential valley fog pre-dawn Tuesday especially kelm. Bgm watches warnings advisories Pa... Excessive heat warning until 8 pm edt Saturday for paz038>040- 043-044-047-048-072.
