...AVIATION UPDATE...

.DISCUSSION...(Today through Sunday)
Issued at 405 AM CDT Mon Sep 6 2021

Quiet weather in the forecast over the course of the next week as
high pressure to our west will be the dominant weather feature and
help keep the local area dry...steering any potential weather
systems well to our north and east. 

As shortwave ridging transitions across the local area
today...expect a rather warm early September afternoon as high
temperatures approach 90 in most locations. This is slightly
warmer than the previous forecast...but in the ballpark of
expectations from the past few days as temps aloft warm and mostly
sunny skies are observed across the local area. Given all the fire
activity to our west...expect some haze in the upper levels of the
atmosphere today...as depicted by the latest HRRR smoke 
runs...but surface visibilities should be unaffected as the smoke 
will remain elevated across the region. 

A weak and dry cold front will transition across the local area
overnight tonight...dropping 850mb temps 6-8C from this afternoons
levels. This should correspondingly drop temperatures back down
closer to 80 for the middle portion of the week...before the high
to our west begins to weaken and sink southeastward towards the 
end of the week as multiple disturbances weaken the northern
extent of the ridge. While temperatures will climb a few degrees 
late in the week as the overall axis of the upper level ridge 
shifts east...temperatures should be modified and remain near to 
only slightly above normal thanks to the weakness in the upper
level ridge across our area. While the upper level flow will
eventually shift and become more zonal late in the period...the
lack of embedded disturbances means dry weather will likely
prevail and the current forecast remains dry through at least next
weekend.
