.DISCUSSION...

A few flurries tonight into Tuesday morning

08z WV satellite shows cyclonic flow centered over Chicago with
north-northeasterly winds over our CWA. Off the Pacific Northwest
coast, another notable upper wave is moving eastward, riding the
northern periphery of a ridge centered over the Great Basin with an
axis of higher heights extending northward a bit to the western
Canadian Prairies.

Today, aforementioned northern extension of ridge will advance
eastward, allowing for temperatures to moderate just a bit as
heights aloft increase.

Tonight into early Tuesday, disturbance west of Cascadia will
advance over the ridge and then dive southeast. Cooling aloft
associated with this wave should lead to a saturated DGZ and
introduce dendrites into the column. However, as the crystals
fall, they look to encounter a very dry 700-900mb layer with the
10.00z HREF mean sounding suggesting that saturation through
the column will be short-lived if it occurs at all. Have
therefore kept snow accumulations out of the forecast and held
PoPs below 15.

Breezy Wednesday

Northwesterly flow aloft becomes predominant by Wednesday as the
upper cyclone to our east finally moves over the Atlantic. 10.00z
GFS suggests that a 45/50 knot 850/700mb upper jet will be present
over the CWA around sunrise with this potentially lingering thru 15-
18z, opening up the possibility for notable surface winds. However,
progged soundings suggest that boundary layer depth will be limited
by a slight inversion at/above 850mb, hampering the ability for
these winds to be brought to the surface. Indeed, 10.01z NBM
probabilities suggest that winds will very likely remain below wind
advisory levels for both sustained winds (0-10% chance to reach 30
mph) and gusts (0-15% to reach 45 mph) but will need to keep an eye
on things, particularly if the 850/700mb jet can linger longer into
the afternoon than guidance currently favors.

Warming trend through Saturday, rain potential next weekend

Heights aloft will build into the latter part of the week with a
transient upper ridge moving over the forecast area Friday into
Saturday. Temperatures may reach 60 both days (5-60% and 25-80%,
respectively). As the next longwave upper trough advances over the
CONUS, rain may (15-45%) occur at times but the progressive pattern
suggests potential for impactful amounts will be very low.

.AVIATION /06Z TAFS THROUGH 06Z TUESDAY/...
Issued at 1144 PM CST Sun Nov 9 2025

A shortwave trough will produce a broken 3 to 7K foot ceiling
overnight. With cyclonic flow aloft, there maybe even a few
flurries. Another shortwave trough will move through the area
on Monday night. The low levels look to remain rather dry, so
ceilings will stay VFR.
