Area Forecast Discussion National Weather Service Reno NV 256 AM PDT Tue Aug 11 2020

SYNOPSIS.

Thunderstorm coverage and intensity increases today. Dry and breezy conditions will develop for Wednesday. The rest of the week will feature a rather typical summer time pattern, with light afternoon winds and a few thunderstorms possible over the weekend.

SHORT TERM (through Thursday Night).

No major changes to the forecast thinking. A trough moves inland today, which will provide forcing for enhanced thunderstorm development. PWATs remain high based off of model soundings in addition to ensemble data, so storms have the potential to produce heavy rain. Pay special attention to recent burn scars which have enhanced flash flood potential. Storm motions increase by late afternoon as the flow aloft strengthens. This could help mitigate the heavy rain potential and also increase chances for dry lightning strikes. Please see the fire weather section below for additional details.

Storms today have the potential to be strong with gusty outflow winds in excess of 50 mph, especially given the modeled DCAPE values of ~1000 J/kg. Hail also remains a threat along with blowing dust from any outflows. If you have plans in the Sierra today, it is best to be off the mountains and/or lakes by no later than noon.

Based on the latest high resolution guidance and HREF, storms are likely to build along the Sierra/Sierra Front today by noon-1 pm, shifting eastward into the late afternoon as the westerly winds increase. This means storms could move off the Sierra and be out of the Tahoe Basin by mid-late afternoon. HREF guidance continues to show high probabilities of storms continuing into northeast CA (near/E of US-395) and far northwest NV through 9 pm. Outflow interactions, however, could cause storms to fire off in various locations.

Much drier air works into the region behind this trough tonight into Wednesday with PWATs bottoming out. This will keep skies clear Wednesday with cooler nights anticipated the middle into the end of the week. Winds will be enhanced (zephyr+ if you will) Wednesday with gusts of 30-35 mph possible north of I-80 Wednesday, 20-30 mph south of there. The wind/low RH combination brings enhanced fire concerns, which are discussed in the fire section below. -Dawn

LONG TERM. Friday onward .

A strong ridge of high pressure is projected to lift northward from the southwest US to the Great Basin from Friday through early next week. This will bring a warming trend, especially from Saturday onward with highs well into the 90s to near 100 degrees for lower elevations, and mid-upper 80s near the Sierra. If this ridge expands farther west, we could end up with with the warmest air mass of this summer, with highs surpassing 100 degrees across more areas in western NV.

In addition to the warming trend, this pattern would lead to increasing moisture and instability across the eastern Sierra and portions of western NV. Some of this moisture may be from decaying tropical systems but regardless of the source, conditions would become favorable for mostly isolated afternoon/evening showers and thunderstorms. Timing and location may vary, but currently the first moisture push appears to favor areas south of US-50 Friday and Saturday. A second round of moisture arriving early next week could bring shower/thunder chances farther north, including the Reno-Tahoe area and possibly parts of northeast CA. MJD

AVIATION.

Very light showers are contributing to random strong and erratic wind gusts early this morning, potentially impacting all terminals along the Sierra Front at times through 5 am. Otherwise, stronger and more widespread thunderstorms are expected today with the potential for 40-50+ kt erratic outflows, heavy rain obscuring terrain, hail, and blowing dust. Storms could start as early as 19z, lasting through 05z.

Thunderstorm chances and rough timing within 10 miles of terminals for today are:

KRNO/KMEV/KCXP: 40% 20z-02z KTRK/KTVL: 20% 19z-23z KMMH: 25% 19z-00z

Winds are likely to be gusty on Wednesday, especially near/north of I-80. Gusts of 25-30 kts are possible.

There is a new wildfire, R-1, located north of KSVE, which may bring haze/smoke impacts to the region. The severity is dependent on fire activity today. -Dawn

FIRE WEATHER.

Main concerns continue to be thunderstorms today followed by dry and breezy conditions on Wednesday.

Tough call today with how likely new fire starts will be from thunderstorms. Storms are going to be wet, with plenty of atmospheric moisture available, but we'll also be seeing an increase in storm motion by late afternoon and abundant lightning. Dry strikes outside of wet cores are certainly possible, and with the current state of the fuels, new fire starts from lightning seem to be rather efficient lately. That being said, we are not expecting widespread dry lightning by any stretch of the imagination and these storms are more likely to put down local areas of heavy rain. With that in mind, will keep the fire watch intact today to keep the "heads up" in place, but am not going to upgrade to a Red Flag Warning. Gusty and erratic outflow winds, potentially in excess of 50 mph, also remain a concern.

Storms should kick off in the Sierra and northeast CA by early afternoon, then push into western NV for mid afternoon and evening hours. High resolution ensemble guidance continues to hint at high probabilities for storms focusing in NE CA (near/east of US-395) into far NW NV this afternoon and into the evening. This could be an area to watch for increased lightning potential.

Conditions rapidly dry for Wednesday with slightly enhanced afternoon breezes. We aren't looking at a big wind event, but 30-35 mph gusts are possible for the northern Sierra Front, northeast CA, and northern Washoe/Pershing Counties. This along with the dry conditions could yield critical fire conditions, which is especially concerning following an active thunderstorm day. A Fire Weather Watch remains in effect Wednesday for this. -Dawn
