Fxus61 kaly 211824 afdaly area forecast discussion national weather service albany ny 224 pm edt Wed aug 21 2019 Synopsis It will become warm and muggy today as a warm front tracks northward. Several rounds of showers and thunderstorms are expected today into this evening, with some storms possibly becoming severe. Additional rain showers are possible on Thursday into Thursday night as a cold front slowly crosses the area. Fair and cool weather is forecast for Friday into Saturday, with isolated showers possible by Sunday as an upper level disturbance passes nearby. Near term until 6 pm this evening Severe thunderstorm watch 609 has been issued for much of eastern new york and western new england, except for the adirondacks, and lake george region through 900 pm. As of 129 pm... We are watching two areas of showers and storms early this afternoon... One across southern litchfield and another across the western mohawk valley. The storm in litchfield should exit in the next hour, while the storms in the mohawk valley are expected to track east and intensify as they move into a favorable environment with 1000-1500 j kg SBCAPE and 30-40 kt of effective wind shear from SPC mesoanalysis. Cams have been inconsistent with forecasting placement timing of convection this afternoon. The activity moving through the mohawk valley is associated with a short wave approaching from the west. Convective mode is expected to be mainly multicells with lines and also some supercell structures given the shear magnitude. The main threats will be damaging winds, however large hail will also be possible with the tallest cores due to the fairly strong deep layer shear. Severe threat looks to be lower across the adirondacks and lake george areas, where extensive cloud cover remains in place, thus limiting instability. In addition, 12z href indicating low level helicity (both 0-1 km and 0-3 km) increasing to over 100 m2 s2 from around the hudson river valley and points east into early this evening. So, an isolated tornado or two cannot be ruled out. Heavy rainfall will also be a threat today, as there is some potential for training backbuilding of cells, despite relatively quick forward movement. Isolated flash flooding may occur if cells train and repeated thunderstorms occur in any location. Otherwise, even non-training cells will easily have the potential to cause ponding of water in poor drainage, urban and low lying areas. It appears the best potential for severe thunderstorms time-wise may be roughly between 2 pm and 8 pm. Highs reaching the mid 70s to lower 80s most areas, although some mid upper 80s could occur if some Sun breaks through at times within the mid hudson valley and lower elevations in nw ct. Short term 6 pm this evening through Friday night Tonight, there still could be isolated to scattered thunderstorms through midnight, as mid level heights continue lowering with the approach of the main trough and surface cold front from the west. Convective chances should decrease after midnight, with patchy areas of fog possibly developing. Lows mainly in the 60s. Thursday, the surface cold front will slowly cross the region from NW to se, with the approach of a positively tilted trough from the great lakes. Isolated showers will remain possible until the front passes, and can not rule out some non-severe thunderstorms across portions of the mid hudson valley and NW ct during the early-mid afternoon hours as href mean mu capes reach 500-1000 j kg. Highs should reach the lower mid 80s in valley areas, and 70s most higher terrain areas. Some upper 80s may occur across portions of the mid hudson valley where downsloping nw winds will be possible. Thursday night, the 00z 21 NAM and ECMWF suggest a wave of low pressure potentially ripples along the frontal boundary to our south. This may allow showers to redevelop and expand as far north as the i-90 corridor. Have indicated slight chance to low chance pops to account for this possibility. Lows in the 50s to lower 60s. Friday-Friday night, cooler and less humid conditions are expected. Still can not rule out an isolated shower Friday with the passage of the main upper level trough cold pool, with chances mainly across northern areas. Highs Friday mainly in the 70s in valleys, with some 60s across higher terrain areas. Lows Friday night in the 50s, with 40s possible across northern areas. Long term Saturday through Tuesday Despite some differences in the modeled flow pattern between the ecmwf and NCEP camps, fairly good agreement that the long term period will have very low probability of hazardous weather. The airmass will likely be fairly dry with model consensus of pwats less than 0.75 inches for the most part except perhaps for Tuesday. The main difference within the medium range guidance is that the last two runs of the ECMWF show a deeper and westward-shifted trough compared with the gfs GEFS mean. The ECMWF suggests this low cuts

off and hovers over the region for Sunday Monday, while the GFS gefs mean shunt the trough eastward and do not develop a cutoff, allowing the upstream ridge to build overhead. The difference in the sensible weather with a cutoff would likely be more cloud cover and perhaps some diurnal showers. At this time, will lean toward the ncep solution noting the absence of GEFS members showing a cutoff. The upshot is a dry forecast for Saturday through Monday with comfortable humidity levels and temperatures near to slightly below normal. Will introduce chance pops for Tuesday as the GFS and some gefs members indicate the ridge shifting east with ascent and moisture return ahead of an advancing trough. Aviation 19z Wednesday through Monday Clouds are breaking for Sun early this afternoon for pou and alb and these breaks are spreading eastward towards psf. This will result inVFR conditions. Gfl remains north of the warm front which should keep MVFR and ifr conditions in place through the afternoon. A line of strong thunderstorms is moving down the mohawk valley with some storms along this line already severe. Damaging winds are the main concern these storms but even an isolated tornado. The main time window for thunderstorms looks to be 20z 21-00z 22 at gfl and alb and then 21z 21-02z 22 for pou and psf. During thunderstorms, brief periods of ifr vsby and MVFR ceilings are possible but outside of thunderstorms expect mainlyVFR conditions with stratocumulus based around 3.5-5kft agl. In addition, winds may shift westerly with strong wind gusts in excess of 30kt. After 00z 22 - 02z 22, showers and thunderstorms will decrease in intensity and coverage. Since winds will remain under 5kts and southerly overnight, some mist and MVFR ceilings or brief ifr ceilings (especially 06z 22 to 12z 22) may develop, especially at kgfl kpsf. Visibility restrictions after 06z are also possible at all TAF with the typically foggier spots at kpsf kgfl seeing ifr vsby. Did not include reduced visibility during this update but future updates may adjust. After sunrise, ifr MVFR ceilings and or visibility should return to vfr as winds shift westerly generally after 13z-15z with the frontal passage. Winds will also increase to 5-10kts with stronger gusts possible during peak heating. Future TAF updates will include the breezy winds. Outlook... Thursday night: low operational impact. No sig wx. Friday: low operational impact. Breezy no sig wx. Friday night: no operational impact. No sig wx. Saturday: no operational impact. No sig wx. Saturday night: low operational impact. No sig wx. Sunday: low operational impact. Slight chance of shra. Fire weather It will become warm and muggy today as a warm front tracks northward. Several rounds of showers and thunderstorms are expected today into this evening, with some storms possibly becoming severe. Additional rain showers are possible on Thursday into Thursday night as a cold front slowly crosses the area. Fair and cool weather is forecast for Friday into Saturday, with isolated showers possible by Sunday as an upper level disturbance passes nearby. Hydrology An anomalously moist airmass will spread back into the region today with pwat values increasing to 1.50-2.00 inches. Numerous showers and thunderstorms are expected to develop in the moist airmass, and any storm will be capable of heavy rainfall. Though individual storms may be fast moving, there is potential for repeated rounds of storms which will lead to the threat of urban poor drainage flooding and possible isolated flash flooding. Isolated showers are possible Thursday, with showers possible across southern areas Thursday night. Mainly dry conditions are expected Friday into Saturday.
