710 FXUS61 KRLX 161724 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 1224 PM EST Mon Jan 16 2017 .SYNOPSIS... A stationary front just south of our area lifts north as a warm front through early morning. Cold front Tuesday night. Another system for the end of the week. && .NEAR TERM /THROUGH TONIGHT/... As of 830 AM Monday... Only minor tweaks made to hourly pop grids. Otherwise, no changes necessary. Previous discussion follows... Area of mainly light rain continues to drift east through the WV mountains as a weak surface boundary meanders through. With slight ridging aloft and little surface focus decreased POPs some through the remainder of this morning. Still...cannot rule out areas of light rain with the boundary in the area. That same story lingers through much of today, with some light rain possible -- especially across the northern CWA and mountains -- but there should be `dry` time too. Temperatures will once again be above normal. As a surface low heads into the western Great Lakes tonight a weak warm front slides through the Ohio River Valley. With some support from a 500mb ripple/ vort max have POPs increasing late this evening and tonight...with likely POPs for the Ohio River Valley and northern WV after midnight. Expecting a warm night tonight...if you can call 40s and 50s warm. Have a non-diurnal trend after midnight as WAA picks up on the southerly flow. && .SHORT TERM /TUESDAY THROUGH THURSDAY NIGHT/... As of 300 AM Monday... A cold front crosses Tuesday for another half to an inch of QPF area wide. Despite the name, the overall atmosphere is quite warm for this time of year and no snow is expected with this front. In fact, we may even see an isolated thunderstorm fire along the front. A strong vort max crosses Wednesday for shower where the highest elevations may see a changeover to snow. We get a brief break Wednesday evening into most of Thursday as high pressure builds. The next system approaches Thursday night. && .LONG TERM /FRIDAY THROUGH SUNDAY/... As of 300 AM Monday... Inclement weather pattern continues with a organized system expected Friday followed by another potentially heavy rain system late in the weekend into early next week. && .AVIATION /18Z MONDAY THROUGH SATURDAY/...
