&& .NEAR TERM /THROUGH MONDAY/... As of 1245 PM Sunday... The dry air has struggled to make inroads into southeast OH and northern WV. Further south, low stratus, fog, and patchy drizzle has greeted folks. While the drizzle will taper off and the fog will lift...the low clouds will persist through the remainder of the day. There is hope that northern areas can lift the bases a bit this afternoon. Temps have moved little since last night with our far reaches into southeast OH seeing temps near the freezing mark. We will await the arrival of that pesky front late this afternoon and evening with increasing isentropic lift once again providing for a miserable night of periods of light rain, fog, and low ceilings. Across Perry/Morgan/Athens...temps may creep down to freezing tonight but chances of precip making into those counties overnight are too small to carry any freezing rain hazard. Something to monitor for though. We will see upper heights begin to build on Monday, but the old front/inverted trof should provide enough low level forcing for areas of light rain in the morning. This should taper off in the afternoon as southeast flow near the surface develops and shakes the off the inverted trof. This should also allow for the low stratus to finally lift in earnest. It will be much warmer with highs running a good 10 degrees above normal. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/...

As of 240 PM Sunday... A band of showers in advance of an approaching cold front will move across the area late Monday night into Tuesday. The weak cold front itself should move through Tuesday night. Some cooler air is expected behind the front on Wednesday.

&& .LONG TERM /THURSDAY THROUGH SUNDAY/...
-- Changed Discussion --
As of 240 PM Sunday... Models continue to have considerable differences in timing with systems for the end of the week and into the weekend, although agreeing on unseasonably warm weather. Therefore, forecast confidence in precipitation chances at any particular time are low.

&& .AVIATION /20Z SUNDAY THROUGH FRIDAY/...
-- Changed Discussion --
As of 100 PM Sunday... Drier air advecting in from the north will allow northern TAF sites to see improvement to perhaps VFR CIGS this afternoon. Meanwhile, southern TAF sites will struggle to improve into MVFR. Areas of light rain will move in late this afternoon from west to east in association from the return of an old frontal boundary. This may allow CIGS to briefly improve into MVFR across southern terminals, before CIGS and VSBY lower once again into IFR and then LIFR. This process will be delayed until after 06Z for northern TAF sites. The boundary/inverted trof will become overwhelmed by developing southeast flow near the surface across the entire region. As such the extent of light rain will decrease during the day Monday as well as a slow improvement of CIGS and VSBY. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z MONDAY... FORECAST CONFIDENCE: Low to Medium. ALTERNATE SCENARIOS: Timing improving and subsequent deteriorating conditions thru the period may vary.
