KEY MESSAGES
* Seasonal temperatures and dry conditions prevail across the area today.
* Above average temperatures, and widespread moderate HeatRisk are expected Monday through Thursday for western NV, with typical afternoon breezes.
* Upper trough potentially arrives by the end of the week, with an increase in winds, lower temperatures and low chances for isolated showers and thunderstorms near the OR border.
DISCUSSION
Fair weather prevails today as a zonal flow pattern continues over the region. Only cumulus clouds are observed across the CWA in visible satellite imagery. Temperatures will be warmer than yesterday this afternoon, but will still be seasonal for the beginning of astronomical summer. Typical winds develop this afternoon generally from the west between 10-15 mph and gusting up to 25 mph.
An upper level ridge centered over the International Border in the Desert Southwest will expand and stretch towards our forecast area over the next few days resulting in a gradual warm trend. Temperatures are expected to peak on Tuesday with afternoon highs in the mid to upper 90s for western NV and NE CA, and in the upper 70s and 80s for Sierra communities. The Chalfant Valley and portions of the NV Basin and Range may reach the century mark. Locations like Fallon, Hawthorne and Lovelock in the lowest valleys have a 40-60% chance of exceeding 99F.
Towards the end of the week, the ridge is pushed south as an upper trough descends towards the PacNW. This pattern change brings an increase in winds, cooler temperatures (potentially back to seasonal), and low chances (10-20%) for showers and thunderstorms near the OR border. However, there is still uncertainty with the models in respect to the timing and placement of this system. So, we'll have to wait and see how this system develops over the next few days.
