(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kpbz 201253 aaa afdpbz area forecast discussion... Updated national weather service pittsburgh pa 753 am est Wed feb 20 2019 Synopsis A wintry mix of precipitation is expected today, before changing to all rain by tonight. Dry weather should return Thursday and Friday under building high pressure. Near term until 6 pm this evening 750 am update: a quick 1 to 2 inches of snowfall has already occurred on the nose of strong warm air advection isentropic ascent. Another 1 to 2 inches of snowfall is possible for areas north of i70. Based on current observations, the transition to sleet and freezing rain is along an axis from roughly zanesville oh towards uniontown pa. This transition 'line' will move northward over the next several hours with a brief transition to sleet and freezing rain in the allegheny county area in the 10-11am timeframe and areas north shortly thereafter. Forecast soundings suggest that near-surface temperatures will warm above freezing by late morning for pittsburgh, so a transition to simply rain will be quick. In the ridges, especially garrett county, expect a changeover much later. Heavy snow sleet freezing rain will occur in those locations. Please use extreme caution if traveling in the mountains today and see the winter storm warning for more details. Previous discussion... low pressure is progged to track from the plains to the upper midwest today, pulling a warm front N across the upper oh valley region. This front, along with increasing moisture and shortwave support in SW flow aloft, will spread precipitation across the region. Snow is expected this morning at the onset. Model soundings and critical thicknesses indicate the snow should change to a period of freezing rain and sleet with warm advection aloft. As sfc temps also warm, a changeover to all rain is expected from s-n. Areas well N of pit, and the higher terrain areas of pa, wv, md, will likely not see this changeover until tonight as cooling SE upslope flow keeps sfc temperatures at or below freezing. Will maintain all winter weather headlines as is. After the changeover to rain, around 1.5 inches of rain is expected near and S of I 70 as a low level jet enhances lift. Lesser amounts are expected to the north. With the saturated ground, and streams already running high, will maintain the flood watch. Gusty SE downslope winds are expected especially across the laurel highlands, though the strongest winds are progged to remain above the temperature inversion. Short term 6 pm this evening through Friday night Rain should continue this evening before the shortwave support and deep layer moisture exit. Any lingering freezing rain ne- se of pit should end this evening as winds veer to the s, ending the cooling upslope flow. The sfc low is progged to track to ontario tonight, dragging a cold front across the region. Not much rain is expected with FROPA itself with upper support already departed. Dry weather is then expected Thursday and |
Friday under building high pressure. A shortwave in SW flow ahead of central CONUS trough should return rain chances late Friday night. Temperatures should average just above seasonal levels. Long term Saturday through Tuesday Rain chances should continue through the weekend as the central conus trough approaches and crosses the region. Dry weather should return Monday under a ridge before a fast moving trough in zonal flow aloft crosses the region Tuesday. Above average weekend temperatures should return to seasonal levels by Monday. Aviation 13z Wednesday through Sunday Ifr conditions prevail for most terminals as moderate to heavy snow has spread across most terminals. A quick couple inches of snowfall will be possible for the next few hours. Beginning with the mgw and zzv terminals, a transition to sleet and freezing rain will occur shortly before turning to just rain by mid morning. This transition will happen just a few hours later at pit, hlg, agc, bvi, and lbe. For those terminals, expect a brief transition to sleet and freezing rain around 10am and then rain shortly thereafter. Duj fkl will transition to all rain in the early afternoon. Precipitation will gradually clear out overnight, however, ceilings will remain low.. Likely in the high ifr to low MVFR range. Southeast wind will also gradually transition to more southwesterly. Outlook Restrictions and gusty wind are expected Thursday with the passage of a cold front. Restriction potential returns with weekend low pressure. 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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
