Area Forecast Discussion
National Weather Service Northern Indiana
242 PM EST Mon Mar 1 2021

.SYNOPSIS...
Issued at 239 PM EST Mon Mar 1 2021

Lows will tumble into the teens tonight as high pressure settles in.
Otherwise, the week ahead will offer dry conditions and seasonable
temperatures.

&&

.SHORT TERM...(This Evening through Tuesday)
Issued at 239 PM EST Mon Mar 1 2021

As high pressure settles in overnight, nearly overhead, lows will
tumble into the teens. Cool northwest flow aloft eases tomorrow in
response to falling 850-mb heights in the lee of the Rockies. With
high pressure now to our east, southwesterly winds will provide a
nice temperature recovery for the afternoon. Look for highs in the
low-40s.

&&

.LONG TERM...(Tuesday Night through Monday)
Issued at 239 PM EST Mon Mar 1 2021

Dry conditions are expected through much of the long term period
with some temperature fluxuations. Zonal flow aloft will give way
to northwest flow locally later on this week as a towering ridge
builds over the Rockies. This will keep temperatures seasonable
(40/25 high/low, roughly). I opted to carry the previous
forecaster`s temps for Friday and Saturday. Thereafter, I offered
a blend of the previous forecast and the latest forecast data in
response to easing northwest flow by Sunday and Monday. We will
keep an eye on a short- wave streaking through far southern
Ontario and into Michigan for the weekend. For now, that track
warrants a dry forecast locally.

&&

.AVIATION...(For the 18Z TAFS through 18Z Tuesday Afternoon)
Issued at 1203 PM EST Mon Mar 1 2021

Shortwave and lake enhancement in cold nw flow may bring a few
flurries or light snow showers with brief visby reductions to KSBN
through 19/20Z. Ceilings, currently variable between high MVFR
and low VFR at both sites, should lift to all VFR by mid
afternoon. Skies will clear out and gusty nw winds will diminish
then into tonight as high pressure settles in.

.IWX WATCHES/WARNINGS/ADVISORIES...
IN...NONE.
MI...NONE.
OH...NONE.
