  (on/off)  Help NOTE: mouseover dotted underlined text for definitionFxus61 kpbz 180028 aac afdpbz area forecast discussion... Updated national weather service pittsburgh pa 728 pm est Sun feb 17 2019 Synopsis A wintry mix of precipitation can be expected through tonight with passing low pressure. Snow showers will linger on Monday, and then a dry and seasonably cold Tuesday is expected under high pressure. Near term until 6 am Monday morning Extended the wsw until 1am for much of the area, as freezing drizzle is developing behind the main precipitation field. Pops have been updated accordingly with current radar trends and hires model guidance. Previous discussion... a typically challenging precipitation type forecast dominates for tonight. Mid-level dry air is still slated to arrive tonight, which will remove much of the ice nuclei and raise the potential of drizzle freezing drizzle. Have kept this in the grids after midnight. An extension expansion of the advisory for this threat is also a possibility. Coverage of more substantial showers will slowly decrease toward morning. Short term 6 am Monday morning through Tuesday Scattered northwest flow snow showers will continue into Monday afternoon for much of the region, perhaps into the evening hours along the southeast ridges. Modest snow totals of an inch or less are foreseen for now given fairly meager moisture in the dendritic growth layer and low inversion heights. However, some decent lapse rates are indicated below these inversions, so the possibility of a few heavier snow showers will need to be considered. Advancing high pressure will cut off the snow showers, and clouds will decrease through Monday night. Some sunshine is anticipated Tuesday, before mid and high clouds begin to increase later in the day. Temperatures through this period will run a bit below seasonal norms. Long term Tuesday night through Sunday Another messy system will move into the region Tuesday night |
into Wednesday and Wednesday night. Many places will likely see both some minor snow and freezing rain accumulation. This storm is already mentioned in the hwo. Model solutions waver on what will happen with the next system. Right now the ECMWF and gfs both show a system that should remain to the south of the region Thursday and Friday, but the GEFS keeps this storm a bit farther to the north. Have hedged with chance pops across the southeast and slight chance pops for most other locations. The next storm system begins to wrap itself together by Sunday morning, moving across michigan and continuing on to the northeast. Considering the storm track, precipitation should generally be rain by day and snow by night. Temperatures will be slightly above normal through the period. Aviation 01z Monday through Friday Conditions will deteriorate to ifr areawide, with potential for lifr CIGS mixed in as a sfc low passes over the region. Given current sfc temps and the lack of notable warming overnight, added freezing drizzle for most sights until the sfc cold front moves through and makes the boundary layer too turbulent for drizzle. Conditions will slowly improve after this frontal passage through the rest of the day Monday. However, the switch to nw flow will aid the development of lake enhanced snow showers which will reinforce lower ceilings and create brief periods of lower visibilities. These factors will likely keep MVFR conditions in the area the entire day. Outlook Brief period ofVFR expected with high pressure Tuesday before the next low pressure system reintroduces pcpn and widespread restrictions Wednesday. Pbz watches warnings advisories Md...

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. |
