.DISCUSSION...

Northwest flow will promote mild, albeit breezy weather today across
the region, characterized by daytime highs in the upper 50s to 60s.
Abundant sunshine will provide enough surface heating to mix
stronger winds aloft down to the surface, resulting in breezy N/NW
gusts of 25-35 mph through the afternoon. Locally stronger gusts up
to 45 mph are likely across portions of Mono and Mineral counties
where pressure gradients are tightest. Be prepared for choppy waters
on Pyramid and Walker lakes, crosswinds along I-80 and US-50, and
bumpy flights into/out of regional terminals.

The upcoming week will feature much warmer weather as high pressure
overspreads the western states. Daytime highs for the Sierra and
western Nevada jump from the mid-60s/mid-70s Monday to the mid-
70s/mid-80s Wednesday. A couple weak low pressure areas will quickly
pass by the region at the end of the week, ceasing our warming trend
and introducing some minor cooling. Winds will be mostly light this
week outside of typical afternoon breezes, but increased winds are
possible Wednesday through Friday with each trough passage. While
much of the week will remain dry, chances of afternoon showers and
thunderstorms may increase for the latter half of the week.

Very early indications lean towards a warmer than normal Memorial
Day weekend, but of course that`s subject to change. It does appear
that odds of another "pesky spring storm on a weekend" are quite
low, but some guidance does keep showers and increased winds on the
table. It is worth pointing out that there is high confidence in
above normal temperatures this week, which likely means regional
waterways will be running fast and very cold leading up to holiday
weekend. So if the warm scenario materializes, do not cool off in
the creeks and streams as they will be very cold and may quickly
induce hypothermia. Be sure to keep checking the latest forecast
over the next few days as we get a better idea of what the holiday
weekend holds weather-wise.
