high pressure directly overhead is making for a very tranquil and
pleasant late august day! highs are expected to reach the upper 70s
today amid mostly sunny skies with light northwest winds. partly
cloudy skies overnight should keep any fog concerns at bay as
radiational cooling should be somewhat limited, although lows are
expected to be in the low to mid 50s again tuesday morning.
with high pressure situated over the great lakes region again
tomorrow, highs will be slightly warmer in the upper 70s to low 80s
as the airmass overhead moderates and winds shift to be out of the
southwest. comfortable humidity with dew points in the mid to upper
50s continues through tuesday.
wednesday is increasingly warmer and humid with 40-60% chances for
rain and storms. an upper level trough will deepen over the great
lakes and a surface cold front is expected to move through during
the day. our area will be in the warm sector out ahead of the front
with increased waa and low level moisture transport from southerly
winds. given the favorable timeframe, highs in the low 80s, and
dewpoints in the upper 60s to near 70, severe weather is possible as
1500-2500 j/kg of surface based instability and decent 0-6 km shear
of 25-30 kts should develop wednesday afternoon and evening. with
the frontal passage during the peak heating hours of the day, at
least isolated severe weather will be possible as spc maintains a
marginal risk (level 1 of 5) for wednesday. 60 mph wind gusts and 1"
hail will be the main threats with multicellular clusters that are
expected to develop but if a few discrete storms can maintain
themselves (low confidence), an all hazards setup may occur.
forecast soundings from the nam, rap, and gfs show varying
amounts of low level shear and helicity, so there are still some
uncertainties to sort through. in the vicinity of the cold
front, 100-150 m2/s2 of srh which would provide enough spin to
support an isolated tornado threat. all of the models have poor
lapse mid and low level lapse rates though, which could indicate
this being a a limiting factor and/or a possible failure mode.
there is still uncertainty regarding exact timing, coverage, and
intensity of storms.
another area of high pressure builds across the midwest and great
lakes late in the week, bringing a return to dry conditions at least
through the first half of the upcoming weekend. have kept low
chances (20-30%) for rain and storms for sunday. temperatures will
remain near normal with a gradual warming trend into the mid 80s for
highs by the end of august.

issued at 118 pm edt mon aug 24 2026
mainly vfr conditions will prevail through this taf period.
however, between 08z and 13z tue, a upper level ridge axis will
push through the area bringing light winds (near calm) and
mostly clear skies which will help to increase chances of at
least patchy mist across the area overnight tonight. with the
almost calm winds think that the lack of mixing will keep the
mist lighter and more patchy in nature with increased dew
production instead so did leave out mention of fg in the tafs
out at this time. mvfr vsbys will be most likely but did feel
kfwa further east of the axis that more mixing may occur and
help to at least temporarily bring vsbys in mist to ifr levels.
a return to vfr with diurnal warming around 14z tue through the
rest of this taf period will occur. winds will remain light and
variable through the period.
