.DISCUSSION...
Issued at 231 PM EDT Thu Oct 31 2024

Intense upper low bringing snow to parts of MN will accelerate out
into sern ON tonight as cold front surges ewd. Broad but decaying
area of light rain overhead in association with prefrontal trough
will fizzle ewd into wrn OH while narrow, broken cold frontal
rainband pivots across the area this aftn with gusty sw winds
behind the front for this evening.

Cool and dry through Sat ahead of next sys deepening invof the srn
Rockies. This sys ejects out into the plains late Mon and then
shears newd into the nrn lakes late Tue, track similar to last
several systems. Rapid uptick in warm advection in tandem with
leading return moisture should foster shower development by Sun aftn
far west yet no slam dunk as wrn flank of persistent ridge is slow
to retreat esp given upper sys track well nw of the area. Will make
some amends to overtly generous pop blended guidance early Sun into
early Mon as warm sector becomes established across the OH
valley with highs back into the 70s Mon. Thereafter weakening
and poorly timed cold front washes east Tue with some lingering
showers.

Rest of the period through into next weekend dry, cool and quiet as
broad high pressure ridges in across the Great Lakes and wrn OH
valley.

.AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...
Issued at 1224 PM EDT Thu Oct 31 2024

Times of VFR light showers/sprinkles will persist pre-frontal to
start as moisture continues to advect in. Cold front is still on
target to swing through KSBN around 20z, and KFWA around 22z. A
thin line of more robust showers (brief vis restrictions) may
accompany this frontal passage with gusty winds to 35 knots
possible. Skies may briefly clear out behind the front into this
evening. However, cooler wnw over the warmer lakes will likely
allow MVFR stratus to drop into the terminals overnight into
Friday morning.
