(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kbuf 271006 afdbuf area forecast discussion national weather service buffalo ny 606 am edt Mon may 27 2019 Synopsis High pressure over southern ontario and quebec will maintain dry and nice weather across the lower lakes for memorial day. Unsettled weather returns Tuesday through a majority of this week as a series of waves of low pressure ripple across the region with chances for showers and thunderstorms. Near term through tonight Early morning fog across the western southern tier will dissipate within a few hours after sunrise. Otherwise, the axis of the surface based ridge to our NW will become centered over southern ontario and quebec today. Meanwhile, a shortwave near james bay will dive southeast across quebec which will send its weakening cold front south into the lower lakes. With limited moisture and support this front will do no more than introduce some mid and high level clouds and a few sprinkles across north central new york this afternoon. With that said, for the most part look for abundant sunshine across a majority of the region and temperatures rising into the upper 60s and lower 70s. Although, if you're headed to the lakes it will be a bit cooler, especially near the shore of lake ontario with a ene wind flow as water temperatures are still in the upper 40s low 50s. Tonight, high pressure over southern quebec will begrudgingly give way to low pressure and convective activity over the upper midwest as it tracks east towards the region overnight. While high pressure slowly slides east into new england it will maintain dry conditions for at least the first half of night. As we head into second half of the night and early Tuesday morning a warm front will punch into western ny with convective chances increasing across the forecast area from west to east. That said, with clouds and the warm frontal arrival lows overnight will more than likely occur early across western ny and then slowly rise with low to mid 50s expected south of lake ontario. Across the north country, where skies will see less cloud cover initially expect lows in the upper 40s by daybreak. Short term Tuesday through Thursday An amplified upper level flow over the us will continue through the midweek period with a low moving very slowly east across the intermountain region and into the plains, weakening a little in the process, while a southeast us ridge moves slowly east. In between, a subtropical jet will force renewed severe convection in the midwest, with remnant mid level (convectively augmented) circulations wafting over the top of the ridge - somewhere over the lower great lakes region, or ohio valley, or mid atlantic region. That is, the forecast confidence for timing and placement of convection over the next several days will be on the low side. Forecast confidence is highest early on Tuesday as the current midwest MCS devolves toward the great lakes by tonight, with its remnant mid level circulation eventually spawning a surface reflection by Tuesday complete with warm front, cold front and warm sector in between. The warm front should be moving through the region on Tuesday with accompanying showers and some thunderstorms, followed by the warm sector for Tuesday afternoon. This is where the forecast confidence quickly starts to deteriorate. It is uncertain how far the warm sector will work into the region and how much clearing will occur. This uncertainty will have an impact on afternoon convection. Current higher res runs focus a lake breeze cold front initiated band quickly south toward pa with potential severe weather along the front. Assuming this works out, Tuesday night would be dry. However, now concerns lie on whether the front moves south into pa or stalls over the region, serving as a boundary for additional convection later Tuesday night and then into Wednesday as the next convective ridge rider approaches the region. So, will keep a chance of showers thunderstorms in the forecast, with renewed convection |
possible with the next system sometime on Wednesday. Again, confidence is low on placement and timing; there should be dry periods in between systems. This scenario repeats again by Thursday, with yet another midwest convective system eventually riding over the southeast us ridge and probably affecting our region with continued uncertainty on location and timing, but with at least a chance for measurable rain over each 12hr period through the midweek period. Long term Thursday night through Sunday The overall pattern over north america during this period will be dominated by an anomalously deep and persistent closed low that will be anchored in the vicinity of james bay. Interestingly... The return interval for such a feature in that area at this time of year is roughly once in a ten year period. The importance of this closed low is that shortwaves rotating about its periphery will not only produce times of unsettled weather during this period... But it will also guarantee that we will not experience any true summer warmth for the foreseeable future. The latter will due to the suppression of the sub tropical ridge that typically resides over the deep south at this time of year. Overall... Temperatures during this period as we head into june will average within a couple degrees of normal. Now some day to day details. Confidence in the forecast for Friday is below normal... As there is a large variance in the projected position of the aforementioned frontal boundary between the medium range ensemble packages. Will raise pops to slgt chc to cover this uncertainty... But am still obviously heavily leaning towards an improving and mainly dry day. High pressure should then build across the region Friday night and Saturday... With fairly high confidence that fair dry weather can be expected. Another frontal boundary on Sunday should support at least the chance for some showers to end the weekend. Aviation 10z Monday through Friday WhileVFR conditions will continue at area terminals, there will be some valley fog in the southern tier this morning. Once this dissipates,VFR is expected at all terminals with high pressure overhead. Tonight,VFR conditions will likely continue through the first half of the night. Later on, a weak low will track east with increasing chances for showers and thunderstorms by early Tuesday morning. Outlook... Tuesday through Thursday...VFR MVFR with scattered to occasionally more numerous showers and thunderstorms. Friday...VFR. Marine High pressure will settle over southern ontario and quebec for memorial day which will provide light northerly winds and minimal wave action on both lakes. Tonight, a warm frontal boundary pushes into the lower lakes with increasing chances for showers and thunderstorms but winds and waves will likely remain below small craft advisories (sca). Chances for showers and thunderstorms will continue through the rest of the upcoming week as a wavy frontal boundary influences the lower great lakes with winds and waves likely remaining just below SCA levels. Buf watches warnings advisories Ny... None. Marine... None. Synopsis... Ar near term... Ar short term... Zaff long term... Rsh aviation... Ar marine... Ar |
