.UPDATE...
The SYNOPSIS...SHORT TERM and LONG TERM Sections have been updated
below.

.SYNOPSIS...
Issued at 247 PM EST Tue Mar 2 2021

High pressure is expected across the area through the upcoming 
weekend.

&&

.SHORT TERM /Tonight through Friday/...
Issued at 247 PM EST Tue Mar 2 2021

Operational and ensemble model data continue to indicate long wave 
ridging will develop over the middle of the country during this 
period. This will result in a quiet weather pattern locally, with 
surface high pressure in control.

A cutoff low, currently off the California coast, is expected to 
undercut the ridge, and approach the Tennessee Valley by Friday.
All guidance suggests any precipitation threat with this feature will 
remain well off to the southwest of the forecast area on Friday. 
Will continue with a dry forecast through the short term.

Progged low level thicknesses generally support the GFS MOS temperature
guidance through the period, so little if any adjustments planned.

.LONG TERM /Friday Night through Tuesday/...
Issued at 247 PM EST Tue Mar 2 2021

Central Indiana will be dominated by surface high pressure over the 
area through the weekend. Very dry column and subsidence supports 
dry weather, while northeast parcels suggest plenty of sunshine will 
be tempered by cold advection and result in seasonable temperatures 
Saturday with highs in the 40s. 

As the high shifts off the southeast early next week, the low level 
fetch will shift to the southwest which will bring warmer 
temperatures to the area starting Sunday when afternoon highs will 
reach the 50s. By Tuesday, lower 60s will even be possible as 
southwest winds pick up a bit and despite increase in cloud cover.

period. Winds will be from 210-250 degrees 7 to 13 knots.
