Area Forecast Discussion National Weather Service Reno NV 1232 PM PDT Mon Apr 29 2024

SYNOPSIS

Mild temperatures and increased breezes are in store today with cooler conditions near the Oregon border. A dry cold front will arrive on Wednesday, bringing another round of cooler weather and breezy winds. Otherwise, much of this week will be dry and seasonably warm until chances of showers increase this weekend.

DISCUSSION

A beautiful late-April day is well underway across the region, featuring mostly sunny skies and mild temperatures. Latest satellite imagery places a southeastward advancing cold front moving through the S OR/N CA vicinity, which will eventually march through the region during the afternoon. As a result, temperatures will be on the cool side near the OR border with widespread breezy west winds shifting to northwest in the post-frontal environment.
Wind gusts of 25-35 mph will be common across much of western Nevada this afternoon into the early evening with some wind prone spots perhaps reaching 40 mph at times. Winds are expected to subside late this evening as pressure gradients slacken.

The remainder of the week will be rather quiet weather-wise with another bout of brisk north winds and cooler temperatures accompanying a dry cold frontal passage on Wednesday. Chilly overnight lows are in store for Sierra valleys and portions of western Nevada Wednesday night into Thursday, particularly from Lassen County into N Washoe County where temperatures will likely fall into the low 20s. Otherwise, daytime highs this week (except for Wednesday) will be seasonably warm as temperatures reach the 60s and 70s for Sierra and western Nevada communities, respectively.

The 12Z suite of ensemble guidance is beginning to converge on a more amplified eastern Pacific trough this weekend, a solution that the GEFS continues to be much more bullish on compared to the ECMWF. Given that the ECMWF is starting to jump on board, confidence is increasing on more widespread and relatively greater QPF totals over the weekend, along with cooler temperatures and gusty winds. Blended guidance suggests a 30-50% chance of QPF reaching a tenth of an inch across the Sierra north of the Tahoe Basin and 15-30% chance of the same threshold for western Nevada. High elevation snowfall is favored to be light with the Sierra crest having a 10-30% chance of seeing 2+" of snow over the weekend.

AVIATION

Generally good flying weather next few days with VFR conditions.
Breezy afternoon and early evening W/NW winds will occur today and tomorrow, leading to some bumps and localized wind shear. Nothing major with surface gusts on the order of 20-30 knots.
