Area Forecast Discussion National Weather Service Reno NV 1205 PM PDT Tue Oct 3 2023


SYNOPSIS

Low pressure slowly exits today with high pressure returning for the rest of the week. Cloud cover will decrease tonight and Wednesday with sunny and warmer afternoons lasting through the weekend.
Breezier winds and chances for showers may return next week.

DISCUSSION

The shortwave that brought light showers to northern Nevada earlier today has quickly ejected east, taking the shower potential with it.
High pressure has begun to take hold across the West, with areas of drier air also migrating into the region, as seen on water vapor satellite imagery. HRRR ensemble is also highlighting the mid to high level clouds clearing out by this afternoon and evening.
Clearing skies will promote colder temperatures tonight into Wednesday morning with some patchy freezing fog for Sierra valleys. We're still keeping an eye on the strengthening easterly gradient for tonight into Wednesday, with gusty winds slated for the northern Sierra ridges (gusts 30-40 mph). There will still be some potential for the elevated winds to mix down to Lake Tahoe level at times with gusts around 20-25 mph.

The slow start to the warm up will kick into gear by the weekend, with forecast temperatures 5-10 degrees above normal. Generally, winds are forecast to be light through Saturday and we will see a return of our near-daily west to southwest breezes as temperatures warm up.

We will be monitoring the more active weather pattern projected to set up for the Pacific Northwest for next week. Extended long range guidance continues to direct the primary track just to the north of the Sierra and western Nevada, but the progressive pattern will lend itself to increased potential for showers and breezes for our region as well as a return back to near average temperatures.
Again, there are no significant storms are showing up for now.

AVIATION

* High pressure taking hold across the West with VFR conditions at all terminals through this evening. There may be some patchy freezing fog in Sierra valleys late tonight and early Wednesday morning, but the easterly gradient may be a limiting factor.

* We're still planning on an increase in east winds across the Sierra ridgelines tonight into Wednesday. Localized light-moderate turbulence is possible, especially for smaller aircraft. Surface winds at the terminals will remain light.

* High pressure will follow the rest of the week with light winds, clearing skies and prevailing VFR conditions.
