Area Forecast Discussion National Weather Service Reno NV 205 PM PDT Tue May 7 2024

SYNOPSIS

Expect breezy winds out of the north through this evening.
Another chilly night is in store tonight into Wednesday morning with near to sub freezing temperatures. A warming and drying trend ensues through the latter half of the week, with above average temperatures expected this weekend.

DISCUSSION

Cool temperatures and breezy north-northwesterly winds will hang on today. Mostly clear skies will give way to excellent radiational cooling tonight, allowing near-to-sub-freezing temperatures to persist in many colder valleys, especially the Sierra. Make sure to protect sensitive vegetation tonight into Wednesday morning if you live in a typically cold valley. A backdoor cold front will pass across the region Wednesday morning, bringing northeasterly flow and the coolest temperatures of the week to the area. Expect highs in the 50s across northeast CA and the Sierra, and low 60s across western NV.

Temperatures will rebound through the end of the week as the upper-level trough that brought us the chillier weather slowly moves east over the Rockies/Intermountain West and an upper-level ridge builds over the northeastern Pacific. Highs will increase near the 80-degree mark across western NV and the 70-degree mark in the Sierra by Saturday. Finally, some spring temperatures! We'll also see minimal chances for precipitation through Saturday.

A blocking pattern along the West Coast will continue to favor above-normal temperatures and typical late-day breezes through early next week. Sunday into Tuesday, the EC-ENS and GEFS show the ridge sliding east over the Intermountain West and Rockies, with a weak upper low forming over southern California. This slight cooling aloft, coupled with increasing PWATs along the western periphery of the ridge has increased afternoon/evening thunderstorm probabilities to 10-20% across northeast CA, western NV, and the Sierra, Sunday through Tuesday. However, forecaster confidence at this time is low to medium, as ensemble guidance has been wavering the past few runs with these isolated thunderstorm chances. We will continue to monitor this situation throughout the week.

AVIATION

VFR conditions will prevail for all TAF sites throughout the week. Surface winds will remain northerly this afternoon and evening with terminal gusts as high as 20 kts. Patchy blowing dust could be a concern over portions of the Basin and Range of western NV this afternoon and evening. Tonight, a backdoor cold front will usher in northeasterly flow that will persist into Wednesday afternoon. Sustained wind speeds will be light with 10-15 kts expected.

Temperatures will continue to warm to above average into the weekend, with chances for isolated thunderstorms possibly increasing (10-20%) by early next week. However, forecaster confidence remains low to medium.
