Area Forecast Discussion National Weather Service Reno NV 309 PM PDT Mon Jun 14 2021

SYNOPSIS.

Winds decrease to more typical breezes Tuesday then become lighter Wednesday and Thursday. Temperatures will rise to above normal Tuesday, warming further to well above normal to even record levels mid to late week and into the weekend. A few afternoon thunderstorms may develop by Thursday and Friday.

DISCUSSION.

Little change with this forecast iteration. The two main features continue to be building heat this week along with low chances for thunderstorms late in the week.

Taking a look at the current conditions, breezes are ongoing with gusts 25-35 mph across much of eastern CA and far western NV. Farther east into the Basin and Range, winds have been lighter but should pick up in the next couple hours as thermal/pressure gradients maximize. The breezes continue to bring fire weather concerns for portions of Mono County; see the fire discussion for more. One feature a tad unusual will be the expectation for elevated winds for foothills and ridges through much of tonight as low pressure approaches the Pac NW coast. In fact, some valleys may see winds remain somewhat elevated for at least a few hours after sunset as the surface pressure gradient only slowly diminishes overnight.

Tuesday will bring similar temperatures as today as a Four Corners ridge remains held at bay as the aforementioned low pushes into the Pac NW. However, unseasonably hot temperatures remain imminent as the Four Corners ridge builds westward across the Sierra and western Nevada Wednesday. The ridge will remain dominant through at least Saturday before there is a slight downward trend (but temps still well above average) becomes in play as the upper ridge weakens some.

* HEAT: Highs will soar to 15-20 degrees above average with record setting heat possible. Looking at 95-105 degrees for lower valleys (mid 80s to around 90 for Sierra valleys) Thursday through Saturday. An incoming band of clouds may temper highs just slightly on Thursday with peak temps possibly Friday. Nonetheless, the difference is only a couple degrees so heat impacts are likely for those exposed to long periods in the afternoon sun. Overnight lows will remain mild in the 60s for most lower valleys (with some 50s in colder lower valleys if skies clear out overnight); however, the wild card is cloud cover by Thursday night. If debris clouds from convection linger overnight as indicated by some simulations (low confidence), lows may remain above 70 in the warmest valleys.

Take extra precautions in preparation for the heat such as limiting strenuous outdoor activity during peak heat and knowing the signs of heat exhaustion/stroke. Heat can be a killer, never leave pets or children unattended inside of vehicles during the heat. LOOK before you LOCK.

* THUNDERSTORMS: Along with the heat comes increased instability and a potential for thunderstorms to develop. Cumulus build ups are possible across mountainous terrain on Wednesday with a few thunderstorms Thursday and Friday, especially along the eastern Sierra north into western NV, especially south of Hwy 50.

AVIATION.

VFR conditions will prevail with the main flight weather concern being gusty surface winds of 30-35kts for Highway 395 terminals. Otherwise, ridge level to surface turbulence has led to +/-10kts gains/losses for the KRNO area today. Ridge level winds will remain gusty through the overnight hours tapering down by Tuesday morning. More typical afternoon wind pattern is expected for the remainder of the week as high pressure builds over the Southwest.

Density altitude concerns increase Wednesday through at least Saturday with triple digit afternoon highs for western Nevada terminals and around 90 for Sierra terminals. Boyd

FIRE WEATHER.

. Red Flag Warning will be in effect this afternoon and evening for gusty winds and low humidity for the Eastern Sierra of southern Mono County .

* Gusty winds resulting from low pressure moving into the northwest United States and single digit RH are ongoing along the Sierra Front of southern Mono County. Critical conditions will continue for valley locations until late this evening. However, winds along mid slopes and ridges will remain gusty into the overnight hours before tapering down prior to sunrise Tuesday morning. Elsewhere, localized critical conditions are occurring in western Nevada while RH remains elevated for Sierra locations from Alpine County northward. Winds will follow more typical patterns Tuesday onward with potential for slightly enhanced zephyr winds again by this weekend.

* Drier air will filter into the region on Tuesday and winds will remain breezy across far northern Washoe County. Areas of critical fire weather conditions are possible in this area, but the limiting factor may be the fuel conditions per our latest update from fuels specialists.

* Beyond Tuesday, winds will decrease as high pressure builds over the region. The Four Corners High will build westward over the Great Basin, bringing well above normal temperatures and poorer overnight humidity recovery to the region. There is a significant chance (>70%) that we will see our first triple digit heat in western Nevada and first 90s in the Sierra.

* Chances of thunderstorms will increase late this week as the heat builds over the region. Currently, Thursday and Friday are the most likely candidates for buildups and isolated thunderstorms. The typical pattern for the Sierra and western Nevada when we get into the triple-digit heat is that we will see at least a few isolated storms over the Sierra, even if the models aren't showing it. With the extreme temperatures, and a chance for lightning, new lightning fires will be likely with any thunderstorms, along with chances for strong outflow winds. Hoon/Fuentes/Boyd
