...SCATTERED SHOWERS AND T-STORMS OVER NRN CA, THE SIERRA, NRN NV 
TODAY NARROWING TO NRN CA/NV TOMORROW...
...DRY CONDITIONS NEXT WEEK WITH WARMING TEMPERATURES...

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

Radar and satellite this morning show an area of scattered 
thunderstorms over nrn CA, the Sierra, and nrn NV. Lightning 
detection has picked up flashes and strikes over those areas as well 
due to mid level moisture and instability. Expect this to continue 
the rest of today into this evening with additional chances of 
thunderstorms over far nrn CA into nrn NV tomorrow. Amounts are 
expected to remain near or less than 0.25", though locally higher 
totals will be possible. A general troughing pattern through the 
weekend will also keep temperatures near seasonal normals before 
high pressure re-exerts itself next week. A ridge will build in 
offshore shifting overhead throughout early to mid next week 
allowing temperatures away from the coast to rise up to 5 to 15 deg 
F above seasonal normals. Longer range ensembles show the potential 
for the ridge to flatten next weekend.
