.METEOROLOGICAL CONDITIONS (FRI PM - THU AM)...

High pressure will build in overhead through the weekend bringing
dry conditions and above normal temperatures through early next
week. Expect temperature anomalies after today of +5 to +15 deg F
with some locations nearing +20 deg F. Not much has changed between
now and this morning regarding the system anticipated to impact the
region mid to late next week. Models continue to disagree on the
arrival timing of initial precip and the speed of its subsequent
movement. Ensemble spread remains high similarly to this morning
with arrival of precip varying from Weds aftn to Thurs aftn.
Afternoon QPF continues to hold back on initial precip compared to
WPC and the NBM but the latest runs look a little more similar to
this morning`s thinking. Amounts for Wednesday have increased by
about 0.10-0.25" along the north coast and over the nrn Sierra.

Afternoon QPF 0.30-0.75" along the coast north of the Golden Gate
(locally 1" King Range), tapering off to 0.10-0.50" inland to I-5
and a few hundredths to 0.25" for the rest of the central coast.
Confidence remains low given model differences and ensemble spread,
expect these amounts to change over the coming issuances.
