651 FXUS63 KIWX 180706 AFDIWX Area Forecast Discussion National Weather Service Northern Indiana 205 AM EST Mon Feb 18 2019 .SYNOPSIS... Issued at 105 AM EST Mon Feb 18 2019 Cloudy with a lingering morning flurry yet continued cold otherwise today with highs 25 to 30. Skies clear overnight with lows in the teens. Another system will bring a wintry mix late Tuesday night through Wednesday morning. && .SHORT TERM...(Today and Tonight) Issued at 205 AM EST Mon Feb 18 2019 Lagging mid level trough and associated moisture plume in the process of re-seeding still moist boundary layer. Expect mainly flurries/very light snow through daybreak north of US 30 and spits of fzdz south. Ridging follows afterward for today yet given how extensive low clouds are upstream, little chance of seeing any sunshine as clearing looks to hold off until after sunset. && .LONG TERM...(Tuesday through Sunday) Issued at 205 AM EST Mon Feb 18 2019 Pesky and persistent split flow regime continues with next wave in the pipeline ejecting out Tue night and through the upper midwest/wrn lakes Wed. Stalled sern US frontal zone will bottle up most of the associated moisture advection while upper wave bifurcates west, essentially splitting the CWA from better associated forcings. Thus a brief period of accumulating snow late Tue night followed by a brief mix Wed morning then rain Wed aftn before ending as warm sector deepens further. Thereafter focus turns toward the weekend as parent sw US upper low finally ejects out and lifts through the lakes. While alot of spread exists yet with sfc cyclone track, composite pattern aloft of a deeper/more phased system would support a farther west track of which puts the CWA squarely in the warm sector. && .AVIATION...(For the 06Z TAFS through 06Z Monday Night) Issued at 1250 AM EST Mon Feb 18 2019 Light snow will continue through the early morning as low level trough pivots through the area in wake of exiting low. Still some low chance for freezing drizzle at KFWA in the next few hours but temps aloft continue to drop and will support better ice nucleation as steadier precip drops south. KSBN resides on edge of better low level moisture and ceilings could bounce around quite a bit through the early morning. Should climb above fuel alternate at both terminals by late morning with some late day clearing possible as drier air is slowly advected into the area. && .IWX WATCHES/WARNINGS/ADVISORIES...
