Areas affected...Northern Montana

Concerning...Snow Squall=20

Valid 072149Z - 080145Z

SUMMARY...Scattered snow showers and strong winds will result in
periods of reduced visibility across northern Montana this afternoon
and into the evening hours.

DISCUSSION...Latest surface observations from southern Alberta show
a cold front pushing south into northern MT. Visible satellite
imagery also shows the southward progression of this front with a
large swath of stratus moving into northern MT. A few surface
observations and web cams from southern Alberta show pockets of
moderate snow under this stratus with marginal visibility
reductions. Blowing snow model probabilities suggest that visibility
reductions down to one mile are possible as temperatures fall into
the low 30s with winds gust to near 30-35 mph and concurrently
falling snow. Latest hi-res forecasts hint that more
widespread/heavier snow showers are possible across northern MT this
evening as low-level lapse rates steepen behind the front, providing
a shallow layer of instability to help locally augment snowfall
rates. This may result in pockets of more substantial visibility
reductions closer to 0.25 mile.

Areas affected...parts of southern Tennessee and northern
Alabama...and into northwestern Georgia

Concerning...Tornado Watch 51...

Valid 020409Z - 020545Z

The severe weather threat for Tornado Watch 51 continues.

SUMMARY...Local risk for severe weather continues across northern
Alabama and adjacent southern Middle Tennessee, within WW 51. With
some risk possibly existing east of the existing watch, we are
monitoring parts of southeastern Tennessee and northwestern Georgia
for possible/new WW issuance.

DISCUSSION...Latest radar loop shows strong thunderstorms crossing
Tornado Watch 51 at this time, including intense/rotating storms
across Madison County AL and Franklin/Marion County AL. As the
low-level jet veers with time, expect ongoing storms to persist for
at least another couple of hours, and given the fairly homogeneous
airmass just east of the WW into the southern Appalachians as in
areas farther west, some severe threat may expand into these areas,
possibly warranting new WW issuance.

Areas affected...northeast Oklahoma into southeastern Kansas

Concerning...Severe potential...Watch unlikely=20

Valid 132331Z - 140100Z

Probability of Watch Issuance...5 percent

SUMMARY...Conditional severe risk through the next couple of hours.

DISCUSSION...Towering cu can be observed near the dryline across
northeastern Oklahoma as of 23z. Convective initiation within this
region has be subdued by a strong mid-level capping inversion in
place much of the afternoon. Surface objective analysis would
indicate some weakening of the mid-level capping north of the I-40
corridor, further supported in cumulus fields across eastern Osage
County and Pottawatomie/Lincoln County. Low level moisture remains
limited, which is likely leading to very high cloud bases. Should a thunderstorm develop, the main threats would be for isolated large
hail and gusty winds. Nonetheless, upper-level support is increasing
across the Oklahoma/Kansas border this evening. Overall, confidence
in thunderstorm development remains low and a watch is unlikely to
be needed.
