.DISCUSSION... (Today through next Monday)
WEATHER PATTERN OVERVIEW: An LPC to the northeast over the northern Rockies migrates eastward early this week and ridging builds over the West Coast and Great Basin. Under a stable, dry atmosphere temperatures will gradually a couple degrees each day to top out in the mid 80s by late week. The ridge will maintain position over the area through late week though as it begins to push east its western flank will open the area of to southerly flow. Coinciding with this shift a low pressure system making its way northward from the Baja of California up the west coast will introduce moisture to the SW CONUS.
Moisture will begin to seep into central NV Thursday night into Friday as PW values climb to around 0.7-0.8 inches over northern Nye and White Pine Counties. By midday Friday enough instability (around 300 J/kg of CAPE) over central and east-central NV will help initiate shower and convective activity. Areal coverage is mainly confined to an area along and south of US-50 with some isolated convection as far north as southeast Elko County possible. A few hundredths of rainfall out of this moisture push is possible over central parts of NV though a widespread rainfall event is not anticipated at this time. Into next weekend model disagreement exists around the positioning and timing of a low pressure system that could bring additional rainfall to the region early next week.
FORECAST CONFIDENCE & DEVIATIONS: With ridging setting in no deviations from the forecast were necessary as the weather pattern over NV will be quiet for several days. NBM is aggressive with areal coverage of rainfall over the region with the incoming moisture push later this week despite model consensus keeping appreciable moisture confined to central and east-central NV. Current thinking is to wait on future model runs before correcting NBM forecast for Friday and Saturday.

.AVIATION...
VFR conditions are expected through Monday night as no precipitation is in the forecast. Afternoon wind gusts on Monday at terminals KEKO and KELY will reach near 20 KTs through evening hours.
&&
.FIRE WEATHER...
High pressure building over the Great Basin will keep the weather fairly benign this week. Afternoon gusts could reach to near 20 mph at times and the region will see a decrease in RH each afternoon. More active weather is possible into next weekend as increased moisture may bring shower and thunderstorm activity to fire weather zones 425/426/427.
