Area Forecast Discussion National Weather Service Reno NV 1226 AM PDT Sun Apr 28 2024

SYNOPSIS

Mild weather will continue today. A couple of dry cold frontal passages will bring cooler weather and breezy winds Monday through Wednesday. Otherwise, this week will be dry and seasonably warm with increasing shower chances next weekend.

DISCUSSION

After a cool, wet Friday, we dried out and warmed back up to average temperatures on Saturday. Our warmup continues today as a weak ridge moves into the region. High temperatures will increase around 2-5 degrees, also ending up about 2-5 degrees above average for late April. Skies will become mostly clear by the late morning, along with typical westerly breezes this afternoon. Overall, it will be a very nice Sunday.

On Monday, a trough will move into the Pac NW with a weak dry front moving through northeast CA/northern NV. For northern Washoe, northern Lassen, and the Surprise Valley temperatures will fall around 5-10 degrees, ending up roughly 4-8 degrees below average. Elsewhere, temperatures will fall to around average for southern Lassen County through the greater Lake Tahoe region, as well as into the Reno metro area. This front will have little effect on temperatures in Mono and Mineral counties, where readings will remain near to slightly above average. North to northwest winds will become breezy during Monday afternoon with this front, with gusts upwards of 30-40 mph from the early afternoon into the evening. A slight 2-4 degree warmup is anticipated for Tuesday, with breezy west/northwest winds once again during the afternoon and evening.

A further cooldown is in store on Wednesday as a trough and cold front drops south through Great Basin, shifting winds to the north. Temperatures will tumble around 5-10 degrees (except remaining at already cool levels near the OR border), leaving the region below average for the first day of May. The trough moves east Thursday with weak ridging returning through early Saturday, followed by some increased winds as the ridge shifts to the east.
Blended guidance warms temperatures back above seasonal averages especially Friday and Saturday. By the end of next weekend, the ensembles fall further out of agreement with either a deep upper low, or more zonal flow/weak ridging. The next chances of precipitation could also return by next Saturday night and Sunday, but confidence remains low.

AVIATION

* Widespread VFR conditions prevail through the next few days.
Today's winds will be generally light for the Tahoe area terminals, with typical west breezes (gusts around 20 kt)
between 21Z-04Z for the other eastern CA and far western NV terminals.

* 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 frame. In addition, sustained west/northwest winds of 15-20 kts with gusts up to 30 kts are expected for the western NV terminals. Meanwhile, Sierra terminals will see sustained west winds of 10-15 kts with gusts to 20 kts.
