Area forecast discussion 
National Weather Service Medford or 
238 PM PDT Wednesday Jul 23 2008 


Discussion...short wave trough brought dry westerly flow aloft 
into the forecast area today. Current visible imagery showing 
little or no clouds...but areas of smoke remain across portions of 
Siskiyou and Modoc counties. A weak ridge of high pressure will 
build into the area tonight and skies will generally be clear. 
This will allow temperatures to drop off nicely and lows should be 
at least a few degrees below normal. Marine stratus not expected 
to be as widespread as last night...but some is expected to 
redevelop along the coastal waters especially from Cape Blanco 
northward and also around Brookings. 


Any marine intrusion tomorrow will give way to sunshine by middle- 
late morning along the coast and the remainder of the region will 
be sunny and dry. Expect temperatures to moderate slightly from 
today's maximums. 


Not much change is expected Friday. GFS and European model (ecmwf) showing another 
trough approaching the coast Friday night into Saturday. Expect 
much of the energy from this system to remain to our north...so 
not going to introduce any precipitation into the forecast. It may 
shave a couple of degrees off maximum temperatures...but again 
overall not much change. 


Beyond that...all indications point to a continued west-southwest 
flow aloft for the second half of the weekend and into early next 
week. This will keep dry weather in the forecast with temperatures 
near to slightly above average.

Aviation...VFR conditions expected all locations tonight... 
however...marine stratus will cause a few hours of LIFR 
conditions at koth and other localized areas along the coast late 
tonight and early tomorrow morning.
