Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0216 AM CST Wed Nov 08 2017
Valid 101200Z - 111200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
Severe storms are not expected across the U.S. Friday.
Upper level flow over the U.S. is expected to become largely zonal
on Friday, as short-wave troughing departing the Southeast advances
into the western Atlantic. Remnants of an upper low will shift
across the Pacific Northwest as a weakening open wave, and an upper
vortex will cross New England and eastern Canada through the period.
Otherwise, broad/flat westerly flow will prevail over the country.
At the surface, high pressure will remain largely in control, though
a remnant front moving slowly south across Florida may focus showers
and a couple of afternoon thunderstorms. Elsewhere, showers and
perhaps a few lighting strikes are expected over the northwestern
states as the weakening trough advances eastward through the period.
