A storm system will gather strength to our south as we progress through the day and into the night.  While central Indiana won’t experience significant impacts from this storm, we’ll indirectly deal with this system with considerable cloudiness and a chilly easterly breeze today.

Our friends to our south (KY and the higher elevations of the southern Appalachians) can expect accumulating snow.  The east TN and western NC mountains will accumulate over 6″ above 5,000 feet late tonight through Monday morning.

The region will be under the grips of a cold northerly flow through the first half of the work week.  Embedded within that air flow will be a couple of upper level disturbances that will drop into the Ohio Valley.  These impulses of energy will help kick off snow showers and localized heavier squalls at times Monday through Wednesday.  Some localized accumulations of a dusting to 1″ will be possible.

High pressure will gain control of our weather Thursday and this will include the start of a nice moderating trend for the second half of the week, including the St. Patrick’s Day weekend.  With full sunshine Thursday, along with WAA (warm air advection) kicking in, we think highs will top out much warmer than the majority of current guidance suggests.  We’ll go with widespread mid to upper 50s Thursday.

Unfortunately, we’ll add more clouds and showers next weekend.  Wet weather will build in Friday and we can’t rule out shower chances Saturday, as well.  Temperatures will warm well into the 60s by St. Patrick’s Day!

In general, we expect 0.25″ to 0.50″ across central IN with showers in the Friday-Saturday time period.
