.DISCUSSION...A few adjustments were made to the forecast. First
was to reduce the coverage area of isolated thunderstorms late
this afternoon and early this evening. Evidence points to the
Mount Shasta area as having the best chance of an isolated
thunderstorm or two. However there is some evidence suggesting
there could be enough instability and moisture for an isolated
cell to pop up in portions of Lake and Klamath County late this
afternoon. Also sky cover has been adjusted lower. Guidance
typically over estimates the amount of cloud cover when high
clouds are present.

High clouds are moving up from the south ahead of an upper low,
but they are rather thin, and the perception is it will be sunny
to mostly sunny today. Afternoon temperatures will be close to
what they were yesterday. -Petrucelli

.AVIATION...15/12Z TAFs...Along the coast, areas of IFR/LIFR are
developing through this morning, mainly north of Cape Blanco. Then,
conditions clear to VFR early this afternoon. Gusty north winds are
expected in the afternoon and evening along the coast as well. For
inland areas, VFR is expected through the TAF period with an
afternoon uptick in winds to ~7-10 kt. -Hermansen

.MARINE...Updated 900 AM Tuesday, April 15th...The thermal trough
strengthens and northerly winds increase this morning, with the
strongest winds south of Cape Blanco. Very steep and hazardous seas
will develop south of Cape Blanco this morning, then spread to
waters south of Cape Arago by this evening. Steep seas will be
present for waters north of Cape Arago, and these conditions will
continue through Wednesday. Occasional wind gusts gusts of 38-42 kt
are possible south of Port Orford and within 30 nm of shore in this
Tuesday-Wednesday timeframe.

Steep to very steep seas look to remain in area waters through the
rest of the week and into the weekend. -Hermansen/Spilde
