.AVIATION...
Satellite & radar pix show some sct precip developing along the
seabreeze/baybreeze. This activity should gradually make its way
inland this afternoon then die off with the loss of heating.
Forecast soundings do show a bit of an inverted-v this afternoon
indicative of the potential for some decent wind gusts should any
strong cells manage to develop overhead. Otherwise, continued VFR
overnight with a landbreeze developing toward morning.
Rinse/repeat on Thurs.  47

.PREV DISCUSSION... /ISSUED 1012 AM CDT Wed Jul 19 2017/
Deep layer weak east-to-west trough was still located over the
coastal areas at mid morning. The upper level ridge has drifted
southward a bit as compared to yesterday and the PW field has
drifted southward in response. Satellite derived PWs are in line
with the area 12Z soundings: 2 to 2.1 inches along the coastal
counties; 1.8 inches over the central counties; and 1.6 over the
northern areas. MUCAPE values range from 3500 near the coast to
2500 over the northern areas. Liked how the high resolution models
keep the best chances along and off the coast this morning with
isolated to scattered coverage mainly from the central areas
southeastward this afternoon. Tweaked the forecast rain chances
and temperatures to account for the latest model trends. 40
