Area Forecast Discussion
National Weather Service Northern Indiana
644 AM EDT Wed Apr 25 2018

Issued at 628 AM EDT Wed Apr 25 2018

Skies will gradually clear today but it will remain breezy and
cool. High temperatures will range from the upper 40s near lake
Michigan to the lower 60s over eastern Indiana and northwest Ohio.
The rest of the week through the weekend will feature mainly dry
conditions and temperatures averaging a little below normal for
late April. This will change early next week as much warmer air
arrives and temperatures look to climb well into the 70s and
possibly even flirt with 80 degrees to start May.


.SHORT TERM...(Today and Tonight)
Issued at 354 AM EDT Wed Apr 25 2018

Lingering moisture along with areas of light drizzle from an
upper low that was over Virgina early this morning will end early
today as a cold front passes and subsidence increases later today.
Highs today will be near 60. A brief intrusion of cold air will
allow lows to dip to near freezing tonight. Have added patchy
frost tonight in this regard.


.LONG TERM...(Thursday through Tuesday)
Issued at 354 AM EDT Wed Apr 25 2018

A second cold front will move across the area Friday with a few
more showers with this system into early Friday night. Moisture
flux ahead of this system should be very limited allowing a
somewhat narrow band of showers to develop along or just ahead of
the front. Patchy frost is likely Friday night and Saturday night
as temperatures drop into the mid 30s. Otherwise, much warmer
weather is ahead with highs rising well above normal early next
week as an upper level ridge builds over the region. Have gone
above the model blend guidance with highs approaching 80 Tuesday.


.AVIATION...(For the 12Z TAFS through 12Z Thursday Morning)
Issued at 628 AM EDT Wed Apr 25 2018

Area of stratus that developed to our west within clear sector is
moving through KSBN early this morning. Cigs were bouncing between
IFR and MVFR. Sfc obs and satellite trends suggest these lower
CIGS may exit KSBN within an hour or two of issuance so may need
a brief tempo group. Should see skies clear with VFR remainder of
period. KFWA similar but will see lower clouds hang around
through mid morning before clearing and VFR. Northwest winds 10 to
15 knots with gusts to around 20 knots expected.


LM...Small Craft Advisory until 2 AM EDT Thursday for LMZ043-046.
