UpdateJanuary 29th, 2013 at 12:00 pm by Chad Evans under Chad's WLFI Weather Blog
A few passing showers & t’storms are still possible today (30%), but overall rainfall coverage will be on the increase this evening-tonight.
High temperatures of 61-66 are likely, but we may not see our maximum temperatures until after dusk with winds gusting to 40 mph from the south.
TONIGHT……..HEAVY RAINFALL & QLCS SQUALL LINE…………..
Widespread rainfall & t’storms are likely tonight with a QLCS squall line, which will race northeast across the viewing area.
Timing of the main squall line would be in the 12 a.m. to 5 a.m. in the viewing area.
I expanded sporadic severe wind gust threat to line up along & west of a line from Winamac to Logansport to Russiaville & Atlanta & westward.
Given dew points pushing 60 & extreme directional & speed shear with +80 mph low-level jet, I cannot totally rule out an isolated, brief EF0 to low-end EF1 tornado that could develop in any LEWP or any meso-vortices in the line.
Areas of flooding in poorly-drained & low-lying areas are likely, as well as fields & some lawns, given 1-2″ of rainfall with isolated 2-3″ amounts. Creeks & streams will come up rapidly & Wabash River to the Iroquois River will rise above flood stage by late week & into the weekend.
TOMORROW TO TOMORROW NIGHT & THURSDAY……………
Rain will end tomorrow morning with dry slot arriving. Temperatures will fall from 40s to 30s, then 20s by evening. Some flurries & few snow showers are possible by evening to tomorrow night & perhaps even Thursday morning, but no substantial accumulations are expected. It will be windy & cold though with lows near 15 by Thursday morning & high temperature of around 22.
