&& .NEAR TERM /THROUGH TONIGHT/... As of 1245 AM Tuesday... Several areas of precipitation expected through the near term as a warm front moves through early this morning, followed by a cold front tonight. Relied fairly heavily on the HRRR and 4k NAM to time these areas of precipitation and sharpen the gradients between areas of precip. These models line up decently with the current radar picture. This includes reducing POPs this afternoon across the southern coal fields. Did still include some isolated thunder chances today...transitioning across the western and then southern CWA. In the wake of the warm front today, temperatures will be unseasonably warm with 60s for most locations across the lowlands. As the cold front crosses to the east late this evening and tonight, temperatures will begin to fall. However lows tonight should remain well above normal. && .SHORT TERM /WEDNESDAY THROUGH FRIDAY NIGHT/...

As of 300 AM Tuesday... Weak cold lobe overhead on Wednesday may bring a few snow showers to the mountains otherwise light rain elsewhere. In between systems Thursday while still quite mild. A warm southern system drifts north on Friday bringing another round of rain with another half to inch of rainfall expected. Still no snow.

&& .LONG TERM /SATURDAY THROUGH MONDAY/...
-- Changed Discussion --
As of 300 AM Tuesday... In between systems on Saturday, next system approaches from the southwest and slides through on Sunday lingering into Monday. Surprisingly, there is fairly good model agreement this far out, so went a little more aggressive with PoPs on Sunday night into Monday. Still a little concerned with the persistent rainfall amounts, but so far have escaped flooding as breaks have been sufficient enough to flush out each systems rainfall before the next arrives.

&& .AVIATION /08Z TUESDAY THROUGH SATURDAY/...
-- Changed Discussion --
As of 1250 AM Tuesday... Messy aviation forecast through today, with areas of dense fog in place as of the very early morning hours. As showers increase early this morning with passing warm front, densest fog should dissipate, but fairly low confidence on just when this will occur. Behind the warm front, southerly winds will be in place from the pre-dawn through today, which should also help to keep dense fog at bay by sunrise. As a cold front approaches from the west, have another round of showers crossing. Cannot rule out a rumble of thunder, but not high enough confidence to include in any TAFs. VFR ceilings expected for much of today, with clouds lowering to MVFR along and behind the cold front late this evening and tonight. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z WEDNESDAY... FORECAST CONFIDENCE: Low. ALTERNATE SCENARIOS: Timing of areas of showers may vary, along with category changes.
