Snowy morning in southern Wisconsin and northern Illinois - above is view of Madison, Wisconsin, and bottom is of Kenosha, Wisconsin, on the lake north of Chicago.
The 12 UTC morning upper-air sounding plot above for TWC shows that PW has gone over an inch. However, there is no CAPE and PW is forecast to plummet again after today. Almost no winds, as we're between the main U.S. trough and a weak closed low over Baja.
Plot above is for 850 mb this morning - note the very strong temperature gradient north Texas and northeastern New Mexico. Blue contour shows position of freezing line at 850. The 500 mb chart below shows how we are currently in the col between the two troughs. The Baja low will drift slowly eastward next couple of days, staying to our south.
WRF forecasts this morning continue to indicate a period of strong easterly winds tomorrow, as the front along the southern High Plains backdoors into our area (color bar for this figure is shown in previous post).
The GEFS 500 mb forecast of the mean height contours (below, valid at 12 UTC next Friday the 15th) indicates the ridge will continue to dominate the western half of the country.
