Fxus61 kctp 211909 afdctp area forecast discussion national weather service state college pa 309 pm edt Wed aug 21 2019 Synopsis A pair of cold fronts will push southeast through the state, the first arriving late today and tonight, and the second later on Thursday. Cooler and much less humid air will move in for Friday and will last through much of the upcoming weekend. Near term until 6 am Thursday morning Cu is reaching critical mass, with radar echoes starting to appear in many locations, now. All is as expected so far. Spc has mentioned the eastern part of the CWA in the mcd, and made mention of 60pct chc of svr wx watch being issued. Will continue to monitor storm development. Main mode of convection still appears to be multi-cell clusters. Expect some heavy rain, but the threat for any flooding would be low outside of places which receive multiple storms. Pwats remain AOA 1.5" over most of the area. The storms should die down rather early this evening, perhaps dying totally by 10 pm. Highest pops will be over the sc and sern sections. Any clearing tonight will cause fog to form, ESP in places which will be wet from rain and have little time to dry up before dark. Expect low clouds to slide into the WRN highlands later tonight, and perhaps get into the central mtns, too. But, will make it cloudiest over the NW third for the time being. Next wave nears by morning, and some very light precip is poss in the NW few counties before sunrise. Mins are a tough call when the cloud fog variables are thrown in. Will hold very close to going fcst which differs little from most guidance with l60s N W and 65-70f se. Short term 6 am Thursday morning through 6 pm Thursday Cold front starts to drop across the area during the day, and may allow the northern tier of counties to be dry after 10-11am. Have painted high pops across the central and SRN counties where the next wave will arrive a little early in the day to make that much thunder N of fig-unv-ipt, but will likely result in some stronger storms thurs aftn across the s. SPC dy2 update at 1 pm has nudged the SRN half into the mrgl risk of svr wx for thurs. Maxes in the u70s-l80s may be a little optimistic for the central counties where clouds may prevail for much of the day, but a fade from m80s SE to u60s NW is a good start. Long term Thursday night through Wednesday Trailing upper trough, the mdtly strong uvvel within the thermally direct re region of an upper level jet MAX will be riding over the secondary frontal boundary that will slow down or stall out temporarily somewhere across central or southern pa as the flow aloft backs Thursday into Friday. Depending on the exact location of the quasi-stnry front and area of enhanced lift beneath the re region of the upper jetlet,

there could even be a few periods of steady light, to briefly moderate rain across central or northern pa and some elevated tsra cores. Rainfall amounts later Thursday afternoon into Friday should total a few to several tenths of an inch. Conditions should improve from west to east late Friday, and into the upcoming weekend. An extensive area of high pressure will bring fair and dry weather to central pa this weekend. Heading into next week, the question will be how quickly can return flow moisture make it back into the area? GFS is rather bullish early next week in contrast to the ECMWF which favors continuation of dry wx. These models seem to agree that developing southeast low level flow may advect clouds into the area which could result in lower highs mon-tue. Given the uncertainty, the day 4-8 ndfd forecast closely follows the national blend of models (nbm) which shows a gradual increase in low chance pops mon-tue. Temperatures over the weekend will be near to slightly below average with pleasant and warm afternoons and comfortably cool nights. Another brief hint of autumnlike air with september right around the corner. As mentioned above, could see temps trend a bit lower early next week before moderating through midweek. Aviation 19z Wednesday through Monday Diurnal CU growing rapidly now as temps have risen nicely where clearing occurred for a short time. Highest chc coverage of showers will be over NW pa (bfd) and in the sc mtns (aoo) in the next two hours. Then, the storms should form elsewhere and slide to the east, giving unv, ipt, mdt and lns a high chc of storms between 20 and 23z. Some storms may linger thru 01z in vcty mdt and lns. Otherwise, the sky may initially clear out everywhere. Then low clouds crud creeps in and or forms over the nw half of the area. Bfd, jst will drop into ifr at least for cigs if not for vsby as well. Maybe aoo unv ipt may dip to ifr for a brief time in the morning. Another round of showers may reach the western mtns before sunrise, but most showers will wait until later in the morning and aftn thurs. The NRN mtns will have the best flying wx on thurs, as a cold front drops southward thru the area, and confines most storms to the S of fig-unv-ipt. But, there is a high chc of MVFR CIGS vsby in jst and aoo thurs. Mdt and lns still have a good chc of storms again thurs aftn eve, and perhaps longer into the night. Drier air arrives thurs night and improves flying weather greatly for the weekend. Outlook Fri... Am fog poss. Chance of showers southern 1 4. Sat-mon... Am fog possible.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
