.SYNOPSIS...
Warm and dry conditions persist through the week.
&&
.NEAR TERM /THROUGH TONIGHT/...
Very dry airmass is in place with ridging at the surface and aloft.
Any diurnal cumulus will be quite limited. Gradual warming trend in
highs will continue.
&&
.SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/...
High pressure remains in control Saturday and Saturday night. Warm
and partly cloudy conditions are expected during the daytime hours
with temperatures topping out in the middle to upper 80s. Despite
temperatures being warm, low dew points prevent the heat index from
becoming a factor. Increased cloud cover may develop Saturday
afternoon as some mesoscale guidance shows an upper level shortwave
moving through.
Saturday night is more likely to feature dry conditions for most
locations despite there being a slight chance for showers overnight
on an upper level shortwave trough. Moisture remains low and forcing
remains weak. Forecast lows are in lower 60s.
&&
.LONG TERM /SUNDAY THROUGH THURSDAY/...
Omega blocking pattern across the CONUS generally remains intact
throughout the extended forecast period. The Midwest region will be
embedded within the amplified H5 ridge, which will be the primary
driver for observing above normal temperatures during this stretch.
Highs are expected to reach the middle 80s to lower 90s every day.
Broad high pressure under this ridge will also help maintain dry
conditions at the surface.
While this stagnant weather pattern will result in highs nearing 10
degrees above seasonal norms, dewpoints will still trend on the
lower side, typically mixing out into the 50s during the late
afternoon when diurnal heating is at its peak. Thus, we won`t feel
much impact from the humidity during this hot stretch.
&&
.AVIATION /17Z FRIDAY THROUGH TUESDAY/...
VFR conditions are expected for the TAF period. Light and variable
winds continue until light southwesterly winds develop Saturday
morning.
OUTLOOK...No significant weather expected.
&&
