1234 AM EDT Sun Aug 13 2017

Issued at 1225 AM EDT Sun Aug 13 2017

High pressure will build into the Great Lakes region early this 
morning and linger through Tuesday providing fair weather. 
A slow warming trend is ahead as the high moves east allowing a 
moist southerly flow to return. A low pressure system moving east 
from the Central Plains will interact with this moisture 
providing a good chance for showers and thunderstorms around 
Wednesday night or Thursday. 


.SHORT TERM...(This Evening through Sunday)
Issued at 219 PM EDT Sat Aug 12 2017

Shortwave dropping south through the flow stirring up some 
showers across eastern portions of Michigan. HRRR suggests as this
drops into mainly NE areas some isolated showers could form. 
Given trends updated earlier for token 20 pop for a few hours 
before rapid decrease in pops. Clearing skies and diminishing 
winds may set the stage for some patchy fog overnight, but 
boundary layer moisture may be low enough to keep fog from 
developing. Will punt to eve shift to monitor trends. 

No sensible weather concerns Sunday with little more than fair
weather cu mainly SE during peak heating. Below normal
temperatures will persist with highs in the middle to upper 70s. 


.LONG TERM...(Sunday Night through Saturday)
Issued at 219 PM EDT Sat Aug 12 2017

Dry weather to persist through at least Tuesday night with models
still varying on exact timing of series of waves starting as early
as Weds afternoon into Friday. Highest pops still appear to be in
the Wed ngt/Thurs window, but somewhat skeptical if likely pops
will work out. Have maintained general consensus for now.
Temperatures will head back towards more normal or somewhat above
normal levels with increasing humidity towards the second half of
the week. 


.AVIATION...(For the 06Z TAFS through 06Z Sunday Night)
Issued at 1224 AM EDT Sun Aug 13 2017

Some patchy ground fog is likely by daybreak. Kept the mention of
3SM BR at Ft Wayne, but limited the duration according to
conditional climatology. The fog will mix out rather quickly with
VFR conditions prevailing. 

Otherwise VFR conditions prevail.
