DISCUSSION
AUGUST SURE IS BRINGING THE HEAT AS WE SETTLE INTO THIS NEW MONTH.
WITH OUR TEMPERATURES SET TO SOAR INTO THE 100S TODAY, OUR FIRST IN
A SERIES OF HEAT ADVISORIES KICKS OFF THIS MORNING, AND WILL BE
THE TREND INTO THE REST OF THE WEEK. THE RIDGE THAT IS RESPONSIBLE
FOR THE HEATING TREND WILL CONTINUE TO AMPLIFY INTO THE WEEKEND,
WITH THE HOTTEST TEMPERATURES FORECASTED FOR SATURDAY, WHEN A
50-70% CHANCE TO REACH 105 DEGREES EXISTS OVER WESTERN NEVADA
VALLEYS IN LOCATIONS SUCH AS LOVELOCK, STILLWATER AND SILVER
SPRINGS. ELSEWHERE, IN THE RENO-CARSON CITY-MINDEN AREA, HIGHS
WILL APPROACH 100-102. THE HEAT WILL EVEN SPREAD INTO NORTHEASTERN
CALIFORNIA, WHERE SUSANVILLE COULD TOP OUT AROUND 103. WITH
OVERNIGHT LOWS IN THE MID 60S TO LOW 70S, THERE WILL BE LITTLE
RELIEF IN EVEN THE COOLER HOURS OF THE MORNING. KEEP ALL HEAT
SAFETY REMINDERS IN MIND THIS WEEK AS YOU GET OUT FOR LOCAL
EVENTS, OR FOR ONE LAST HURRAH OF SUMMER FOR THOSE GEARING UP FOR
THE NEW SCHOOL YEAR.
ANOTHER THING TO KEEP IN MIND AS YOU ARE OUT AND ABOUT IN THE AREA
WILL BE PERIODS OF SMOKE AND HAZE FROM NEARBY FIRES. WHILE THE
WESTERLY WINDS WILL HELP TO CLEAR THE SMOKE THAT WAS CARRIED FROM
THE NORTH ON OUR RECENT NORTHERLY WINDS, IT WILL ALSO BE CARRYING
WITH IT SMOKE FROM A NEWER FIRE IN CENTRAL CALIFORNIA (GANN FIRE).
AS FOR WINDS, THE MAJORITY OF THE REGION WILL SEE TYPICAL ZEPHYR
WINDS TODAY WITH GUSTS OF 15-20 MPH THIS AFTERNOON.
A 5-20% CHANCE FOR SHOWERS STARTS TO APPEAR ON THE MONO AND MINERAL
COUNTY AREAS AS EARLY AS SATURDAY, BUT FRIDAY WE MAY START TO SEE
THE CLOUDS AND VIRGA SHOWERS APPEAR. CHANCES CONTINUE TO SPREAD
NORTHWARD ON SUNDAY WITH SOME SHOWERS MAKING IT AS FAR NORTH AS
US-50. THIS INTRODUCTION OF SHOWER POTENTIAL MAY LINGER INTO NEXT
WEEK, BUT WHERE THE SHOWERS WILL SET UP IS LESS CLEAR. THERE ARE
SIGNALS OF THE RIDGE NUDGING EASTWARD, WHICH MIGHT TAKE THE
MONSOONAL MOISTURE ALONG THE PERIPHERY A BIT TO THE EAST AS WELL.
HRICH
AVIATION
* VFR CONDITIONS CONTINUE TODAY AND THURSDAY, WITH WESTERLY GUSTS

KTS THIS AFTERNOON. SMOKE AND HAZE FROM AREA FIRES MAY IMPACT
SLANTWISE VISIBILITY AT TIMES FOR KTRK/KTVL/KRNO/KCXP/KMEV.

ALTITUDE CONCERNS. HRICH
