Complicated Forecast with Minor Snowfall Accumulations Tonight (Up to 6″ In Southern Indiana As System Merger Occurs Farther West)

TODAY:  COMPLICATED FORECAST DAY WITH 1.1″ OF SNOW WITH MODERATE TO HEAVY BAND IN NORTHWEST COUNTIES…………..THICK OVERCAST REMAINS…………

Today has been a complicated forecast day.  Low clouds have hung on, keeping us in the upper 20s all night, though we are as high as 36 right now.  Parts of western Ohio dropped to 8 lastnight with clear skies & freezing fog/frost.  It shows you what clear skies & calm winds can do to your temperature with snowpack & it shows what a low stratus deck under an inversion can do.  They act as a thick blanket.

Dynamic forcing & frontal forcing for snowfall continues to occur to our north & some of this forcing has brought a quick wave of moderate to heavy snow in Newton & Jasper County.  Up to 1.1″ has been reported from Newton County with 0.5″ in Pulaski to northwest White counties. 

Meanwhile, deep tropical moisture is surging northward from Missouri.

TEDIOUS, BIT COMPLICATED FORECAST TONIGHT AS POLAR & SUBTROPICAL JETS MERGE SOUTH OF HERE WITH WIDESPREAD SNOW BLOSSOMING (ESPECIALLY SOUTH & SOUTHEAST OF HERE)………..

A system merger of the two is likely tonight with minor snowfall accumulations across the area, but it is a close call as to how much.  Where the merger takes place will determine how much we get.  STILL thinking southern Indiana may get as much as 6″ tonight.

So, the 0.3-1.1″ in our northwestern & northern counties so far may have a bit more added to it tonight on the order of 0.5-1.1″.  That would give our north generally 1-2″………..perhaps 3″ of total snowfall.

For everyone else near 1″ will do, EXCEPT in the south, where over 1″ to 2″ will likely fall.
