AREA FORECAST DISCUSSION National Weather Service Charleston WV 235 PM EST Sun Dec 15 2019
SYNOPSIS. Strong system approaches tonight into Monday with a wintry mix north transitioning to a heavy rain and flooding threat through Tuesday.
NEAR TERM /THROUGH MONDAY/. As of 230 PM Sunday .
Nose of a strong H850 low level jet currently just exiting northern Arkansas will arrive in western portions of the forecast area this evening. Convergence associated with this feature will kick-off an extended period of precipitation this evening. Warm air advection with the feature will cause some initial precipitation type issues with snow across the northern half of the forecast area transitioning to sleet and freezing rain through the early morning hours and then all rain by mid-morning. Total snow accumulations of 1 to 2 inches and total ice accumulations of mainly a light glaze with localized accumulations up to a tenth of an inch.
By mid-morning any lingering wintry mix transitioning to all rain with the focus turning to potential high water issues. Plume of near climatological maximum moving average (based on ILN proxy sounding) precipitable water values with associated with the aforementioned low level jet will be sitting over us through Monday evening. The right entrance region of an H250 150KT jet over the Eastern Great Lakes will provide strong background ascent atop a somewhat more narrow ribbon of frontogenetical forcing. Total rainfall values through Monday night will fall mostly into the 1 to 1.5 in range with rain continuing into the short term period.
SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/. As of 151 PM Sunday .
Low pressure system to track across southern WV and up through the Greenbrier valley Monday night and Tuesday, then finally exiting Tuesday night. Good jet dynamics and good moisture feed with PWs between 1.25 to 1.75 with this system. Expect axis of heavy rain between 1 to 3 inches to set up from Ern Ky into central WV and then across NE WV. Either side of that axis could see anywhere from 0.75 to 1.50 inches. 3hr FFG across the region ranges from an 1 to 2 inches. So issued a Flood Watch for the entire area except for Perry and Morgan Counties in SE OH, as those counties are expected to see less rain with a sharp precip gradient.
Cold front from this system moves through Tuesday with much colder air behind the front. Some lingering precip could change back to snow before ending across the area late Tuesday night and early Wednesday morning. Upslope snow showers may linger in the WV mountains on Wednesday, with flurries possible elsewhere.
LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. As of 215 PM Sunday .
Quiet end to the work week expected as high pressure moves eastward across the area on Thursday and Friday. Another system is expected to move into the area on Saturday bringing a light mix bag of precip for the weekend and possible snow showers for the WV mountains on Sunday.
AVIATION /20Z SUNDAY THROUGH FRIDAY/. As of 230 PM Sunday .
Any lingering MVFR ceilings briefly improve to VFR late this afternoon. Increasing moisture ahead of a potent storm system will yield decreasing ceilings and increasing precipitation chances through the evening/overnight hours. IFR cig/vis impacts possible at PKB/CKB/EKN by 06-08Z, but think IFR holds off for the remaining terminals through at least early Monday morning.
HTS may briefly see a few snowflakes mixing in this evening prior to transition to rain. More significant impacts at CKB/PKB/EKN possible with enough warm air moving in aloft to transition snow to sleet and/or freezing rain prior to switching to all rain by late morning. PKB may see a little break in the rain during the day Monday, but remaining terminals will see continuous light to moderate rainfall through beyond this TAF period.
Westerly surface winds this afternoon turn light and easterly overnight (except southerly around 5KTs at BKW/EKN). Increasing low level jet may create some LLWS concerns around HTS/CRW/BKW early Monday, but confidence not high enough to include in the TAFs at this time.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z MONDAY . FORECAST CONFIDENCE: Medium.
ALTERNATE SCENARIOS: Timing of onset of precipitation tonight may vary by a couple hours. Timing of deterioration to IFR in SN and RA early Monday may vary.

I do not sell or share any user data or anything else for that matter. I do not keep site logs longer than I need to to keep bad actors off the site. Basically, I delete them after looking at them.

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.
