Fxus61 kctp 240353 afdctp area forecast discussion national weather service state college pa 1153 pm edt Fri aug 23 2019 Synopsis A large area of high pressure over the great lakes will drift gradually to the east, reaching northern new england on Sunday. This weather feature will bring us a several day string of dry and cooler weather with low humidity right into early next week. Near term until 6 am Saturday morning Quiet weather pattern for the rest of the night with partly cloudy skies and cool temperatures making for nice sleeping weather just about everywhere in the cwa. A bit of patchy ground fog by sunrise in the deepest valleys. Short term 6 am Saturday morning through 6 pm Saturday Fog burns away after an hour or two, and a mostly sunny day results. Just a few CU over the mtns. Modified cp airmass visits for the weekend. Tough to beat guidance on maxes on days like sat. Mixing gets up near 8h where temps are 6-9c. We should end up in the u60s across the higher hill tops of the west and north, and m70s in the warmer valleys of the east. These values are generally 4-8f below normal. Long term Saturday night through Friday Patchy valley fog is possible once again Saturday night, as high pressure provides mainly clear skies and light winds. Any fog should burn off quickly Sunday morning, giving way to partly to mostly sunny skies. Temperatures will remain slightly below normal for late-august. Heading into next week, the main question will be how quickly return flow develops and brings moisture back into the area. The GFS continues to be a bit more bullish, although it is slowly coming more in line with the ECMWF in keeping central pa mainly dry until Tuesday. Given the uncertainty, went with a

model blend and gradually increase pops later Monday into Tuesday. Pops should peak on Wednesday with a frontal passage, with a drying trend for the later part of next week. The temperature forecast is less certain early next week, as an increasing southeasterly low-level flow may advect some clouds into the area and result in another relatively cool day on Monday. Some moderation in temps is expected ahead of an approaching cold front tues into wed. Following the midweek frontal passage, cooler and drier weather should return late next week. Aviation 04z Saturday through Wednesday High pressure and associated dry air mass will build southeast from the grt lks tonight and Saturday, providing the region with mainlyVFR flying conditions and light north to northeast winds. The only exception will be in the valleys of central pa, where late night valley fog is very likely. Kbfd is the most likely airfield to be affected, with odds of ifr conditions close to 50 percent. Latest lamp and namnest support onset of valley fog around midnight and dissipation by around 14z Saturday. Outlook Sun... Am valley fog likely northern pa. Mon... Am valley fog possible. Tue... Am low CIGS possible. Wed... Showers and am cig reductions possible. Ctp watches warnings advisories None. Synopsis... Ross dangelo near term... Ross dangelo short term... Dangelo long term...

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
