AREA FORECAST DISCUSSION National Weather Service Charleston WV 1023 AM EST Fri Jan 24 2020
SYNOPSIS. More widespread rain Friday with rain and snow showers lingering into the weekend, transitioning into an upslope snow event at the end of the weekend, most likely in the mountains.
NEAR TERM /THROUGH TONIGHT/. As of 1015 AM Friday .
Forecast generally in good shape. Several bands of showers will pivot through for the remainder of the afternoon with the final one associated with the actual cold front late this afternoon and into early evening hours. Rainfall amounts may exceed an inch across portions of southeast OH and especially northern WV this evening which may result in localized high water. Some of the usual trouble creeks in southeast OH will have to be monitored for exceeding bankfull tonight as well.
Temperatures today were reworked using HRRR as a base which shows the usual downslope compressional warming effects from strong southeast flow. 50-60 kt low level jet will remain in place until the front arrives, though much of this will remain aloft given WAA upglide. Some downslope gusts to 35 kts on the west facing slopes are possible, however, and along the highest ridges in Pocahontas/Randolph counties where a wind advisory remains in effect.
As of 630 AM Friday .
Made minor changes to temperature and dew points this morning to reflect current observations. Lower levels of the atmosphere appear to be moistening in eastern Kentucky this morning, allowing for some rain to make it to the ground near the HTS airport. POPs will continue to increase over this particular area and further down the line today through the remainder of the forecast area.
As of 300 AM Friday .
Nearly-stacked upper level low meandering around the Mississippi River Valley will be the culprit behind today's active weather. At the time of writing, current observations show dew points still portraying dry air in the lowest levels of the atmosphere. Rain aloft will take some time to overcome the dry low levels, so precipitation overnight will be light to start off, becoming more prominent after sunrise along the Ohio River Valley and up the eastern fringes of the forecast area in the mountains once the atmospheric column moistens.
In typical fashion, the positioning of the low will cast a rain shadow upon portions of central and northeastern West Virginia for the first half of the day, then gradually filling in with higher POPs as the afternoon wears on. This area will achieve the warmest afternoon highs into the mid 50s, while the mountains and southeast Ohio will struggle to escape the 40s due to rain overhead, depleting efficient warm air advection from taking place. On the topic of temperatures, Friday morning lows over Randolph and Pocahontas Counties may allow for mixed precipitation to fall before switching over to all rain by midday. Maintained the trend started by previous forecasts with no chance of freezing rain during this time, so chose to hold off on any winter headlines. A similar event of rain/snow showers over the mountains is progged for overnight Friday into Saturday.
Strengthening low level jet accompanying the aforementioned low will punch into Central Appalachia by Friday afternoon, translating to very strong wind gusts over the highest elevations of our mountain counties. Forecast soundings and central guidance both suggest gusts possibly as high as 50 mph over the ridgetops if full momentum transfer is realized. Elected to go with a Wind Advisory starting Friday morning, aligning with WFO Blacksburg and Pittsburgh's Advisory in effect for the same timeframe.
SHORT TERM /SATURDAY THROUGH MONDAY NIGHT/. As of 220 AM Friday .
Some chances of precipitation will continue through most of the area Saturday morning as a low pressure system north of the area moves to the northeast. Precipitation will fall as mostly rain, with chances of snow in the mountains, however, accumulations of precipitation will be relatively low due to the low moving off to the northeast. Chances of freezing rain may be possible in the mountains Saturday morning, but these chances will transition to snow in the afternoon. The chances of precipitation Saturday night will be more of a mix of rain and snow throughout the area. The mountains will have the highest chances of precipitation Saturday night with upslope snow, continuing throughout Sunday into Monday and dissipating by Monday night. There is disagreement in the models over a possible southern system Sunday into Sunday night, possible grazing the southern counties. However, due to various models, confidence remains low on whether this will happen.
LONG TERM /TUESDAY THROUGH THURSDAY/. As of 220 AM Friday .
Models start to show much more disagreement during this period. Tuesday should be dry with a possible system affecting the area sometime Wednesday through Friday.
Each of the models show small disturbances crossing the area Wednesday, however the timing of these differ between the models. The GFS and ECMWF have a ridge over the area on Thursday while the Canadian has a disturbance over the area. On Friday, both the GFS and ECMWF show low pressure systems, approaching from the west, north of the area Friday. The ECMWF shows the low higher to the north than the GFS shows. The Canadian only shows a small disturbance around the area at that time. Overall, there is a possibility of precipitation for this part of the period, however, there is low confidence in the timing and the type of precipitation that will occur.
AVIATION /15Z FRIDAY THROUGH TUESDAY/. As of 640 AM Friday .
VFR will open up the period for a fleeting time this morning before MVFR CIGs maneuver their way into the Ohio River Valley and the higher terrain. Portions of central and northeastern West Virginia will hold onto VFR conditions into the afternoon before succumbing to MVFR by late tonight. Strongest signals for visibility restrictions comes with the frontal passage late tonight as well as with heavier rain bands. A secondary drop in visibility plagues the Ohio River Valley region for the new Zulu day Saturday with wrap around moisture from the low pressure system. The mountains will also see a drop into IFR or worse overnight tonight.
Strengthening low level jet over the region today will inflict strong wind gusts during the day. Maintained LLWS for a few more hours this morning while the nocturnal inversion holds on by a thread, then introducing wind gusts at all terminals aside from HTS and PKB after sunrise. Gusts could approach 25 to 30 knots in the afternoon, subsiding overnight.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 12Z SATURDAY . FORECAST CONFIDENCE: Medium.
ALTERNATE SCENARIOS: Winds may be stronger than currently forecast at terminals outside of mountains. Timing of MVFR or worse conditions may vary from forecast.
