Area Forecast Discussion National Weather Service Reno NV 131 PM PDT Sat Apr 27 2024

SYNOPSIS

Mild weather is expected this weekend aside from a slight chance of showers tonight near the Oregon border. A couple of dry cold frontal passages will bring cooler weather and breezy winds Monday and Wednesday. Otherwise, this week will be dry and seasonably warm with increasing shower chances next weekend.

DISCUSSION

A mostly sunny day with mild temperatures is underway across the region with the exception of some considerable cumulus development shrouding sunshine across Pershing and Churchill counties. Highs today will be right around normal for late May with Sierra and western Nevada locales reaching the 50s and 60s, respectively.
Increasing cloud cover and shower chances will accompany a subtle upper shortwave passage/weak mid-level height falls tonight with best chances (20-40%) of light rain across Lassen and N Washoe counties after 6 PM PDT.

Sunday will feature widespread dry conditions with a brief warm-up before a quick-moving upper trough and attendant dry cold front temporarily cease our warming trend on Monday. Winds will shift to NW/N in the wake of the frontal passage with gusts of 30-40 mph across much of western Nevada Monday afternoon. While this cold front will likely remain dry, there may be some light showers near the Oregon border contingent upon the southern extent of the upper trough.

The remainder of the week is favored to be quiescent as there is a lack of a precipitation signal until perhaps the weekend. Instead, periods of breezy afternoon and near-normal temperatures will headline the weather across the region this week with another dry cold frontal passage/cooldown on Wednesday. In the long term, there is still much disparity between the 12Z suite of ensembles with the GEFS stubbornly sticking with a higher amplitude trough in the eastern Pacific next weekend compared to the ECMWF solution. It appears we are in for a cooler, wetter pattern during the first week of May either way, but to what extent is uncertain at this time.

AVIATION

Widespread VFR conditions prevail through the weekend with the exception of BCFG potential at KTRK Saturday morning. A dry cold front will induce a wind shift (W to NW/N) Monday afternoon, so there may be an attendant increase in LLWS during this time.
