Area Forecast Discussion
National Weather Service Northern Indiana
Issued by National Weather Service INDIANAPOLIS IN
259 PM EDT Thu Apr 19 2018

Issued at 259 PM EDT Thu Apr 19 2018

High pressure will provide quiet weather for the area through the
weekend. A couple of upper level systems will bring a return of
rain chances early to mid-week next week. Temperatures will
moderate into the 60s into the weekend, then cool a bit when the
rain chances move in.


.SHORT TERM...(This Evening through Friday)
Issued at 259 PM EDT Thu Apr 19 2018

Skies were mostly clear across the area this afternoon with high
pressure and subsidence moving in. The cumulus field has moved off
to the south. Temperatures had warmed into the upper 40s and lower
50s for most areas, but cooler readings were near the Lake.

Quiet weather will continue through the short term as high
pressure builds in at the surface, and upper ridging moves in

There may be some passing high clouds at times, but overall skies
will be mostly clear through the short term.

Winds will diminish into this evening with the high moving in.

With mostly clear skies and decreasing winds, went toward the
cooler of the models for lows, which puts most areas in the upper
20s. A model blend looks good for highs Friday with some sunshine.


.LONG TERM...(Friday Night through Thursday)
Issued at 259 PM EDT Thu Apr 19 2018

Dry weather will persist through the weekend, as an upper low will
remain well to the south of the area. There may be some increased
clouds at times, but no precipitation is expected.

Early next week a weak upper low will move into the Ohio Valley,
and this will bring some low chances for rain to the area. Mid-
week, a stronger upper low in the northern flow will move in and
bring better forcing. Thus went chance PoPs mid-week. The system
looks to be far enough east on Thursday to go dry then.

Temperatures will moderate in the 60s by Sunday into Monday, but
as the upper systems move in with clouds and rain chances,
readings will cool back into the 50s for highs by mid-week.


.AVIATION...(For the 18Z TAFS through 18Z Friday Afternoon)
Issued at 1244 PM EDT Thu Apr 19 2018

VFR conditions are expected through the period.

Only a few cumulus are expected near KFWA early in the period,
otherwise clear skies will be the rule thanks to high pressure
building in.

Winds will still gust to around 20kt this afternoon, but they will
diminish by early evening with winds becoming less than 10kt


LM...Small Craft Advisory until midnight EDT tonight for LMZ043-046.
