(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kpbz 231437 afdpbz area forecast discussion national weather service pittsburgh pa 1037 am edt Thu may 23 2019 Synopsis The risk for showers and storms will continue during the late morning with the passing a pre-frontal trough. Additional showers storms are expected later this evening with a cold front passing. Near term until 6 pm this evening Late morning: showers and storms will continue for the next few hours as a pre-frontal trough passes through our region. The biggest threat with these storms is damaging winds. Gusts up to 60-70mph have been reported near the shores of lake erie over the last few hours. Hi-res models display a region of high low level winds (50kts), at 850mb, across northeastern ohio northwestern pennsylvania and help support the reasoning of these nearby storm reports. Storms will gradually fizzle out after lunch time as the upper-ridge, positioned direction over our region, flattens. As we move into the late afternoon early evening, the flattened upper-level ridge is expected to tilt and northwest flow will dominate. As cooling increase aloft, upper-level instability will too increase. By 4 to 6pm a cold front will push over lake erie and move southeast. Severe storms will once again fire up along the boundary. Storms may produce damaging winds, hail, and or isolated tornadoes this evening. Earlier discussion: two periods of showers and storms are expected today, one this morning and a second this afternoon and evening with the cold front. A pre-frontal trough will cross the area this morning. This energy will induce upper level height falls as it moves through, which will eventually assist in frontal passage late in the day. The convection this morning will be encountering a relatively stable atmosphere, and should remain below severe levels. Stronger convection is expected this afternoon, along and ahead of a southeastward moving cold front. Still seeing model differences on timing, placement, and overall intensity of the convection. Atmosphere will quickly destabilize behind the morning shortwave, and plenty of moisture will be available as dewpoints rise into the mid to upper 60s. Winds aloft will become north of westerly, allowing for a cool down at the upper levels, increasing elevated atmospheric instability. However, the mid-levels will remain warm, helping to keep the atmosphere capped until the front arrives. Another limiting factor will be how much cloud cover is left over from the morning rain. Residual cloud cover will limit surface temperature rise and perhaps prevent achievement of convective temps. Models are indicting a break behind the morning |
rain, and what the atmosphere does, in terms of cloud cover and increased buoyancy, during this break, will be critical to storm development along the front. Forecast soundings are portraying a strengthening wind field aloft increasing the threat for damaging wind gusts, and the increase in shear will also create a scenario where convective updrafts can become stronger and long lived. All of these elements will need to be closely monitored throughout the day. Short term 6 pm this evening through Saturday The cold front will pick up speed and approach my southern border late this evening. Activity will end from northwest to southeast behind the boundary, and cloud cover will decrease in the same manner. Height rises and a weak surface high will keep Friday dry. Shower and storm chances will ramp up again Saturday afternoon as the next shortwave rides over top of the upper level ridge. Long term Saturday night through Wednesday The long term will be dominated by the strength and placement of the eastern CONUS ridge. The area will lie on the northern periphery of said ridge, meaning the warm and active pattern will continue. Aviation 13z Thursday through Monday With the band of pre-frontal showers storms moving in this morning, a few sites may drop down to MVFR for a short time. However,VFR will prevail for the majority of the day. As we move into the late evening, a cold front will push off lake erie and move south. Showers storms are expected to form near or along the boundary. As far as timing, confidence is highest in the 21-00z for t'storms near the pit area terminals. Ifr restrictions will be possible with heavier rain storms. With lower confidence in thunderstorm timing and coverage, have included only vcts for Thursday afternoon. Winds will veer from southerly to westerly throughout the period, gusts are expected to reach 25 knots by mid-morning. Outlook Periodic restrictions are possible through the weekend as disturbances round the upper level ridge. Pbz watches warnings advisories Md... None. Oh... None. Pa... None. Wv... None. |

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. |
