DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0136 PM CDT THU JUL 28 2016

VALID 291200Z - 301200Z

...PORTIONS OF THE GREAT BASIN AND SIERRA NEVADA RANGE...
THE ONGOING ISOLATED DRY-THUNDER AREA IS MAINTAINED WITH A
NORTHWESTWARD EXPANSION TOWARDS THE NORTHERN SIERRA RANGE...AS
MOISTURE CONTINUES TO STREAM POLEWARD ALONG THE WESTERN PERIPHERY OF
A MID-LEVEL RIDGE. STORM MOTIONS WILL BE FAIRLY SLOW ONCE
AGAIN...BUT THIS SHOULD BE OFFSET BY A FAVORABLE THERMODYNAMIC
PROFILE AND VERY DRY FUELS. IN TURN...LIGHTNING SHOULD BE RELATIVELY
EFFICIENT AT INDUCING NEW FIRE STARTS.

OF NOTE...A THUNDERSTORM OR TWO IS POSSIBLE FARTHER NORTHWEST ACROSS
THE SOUTHERN CASCADE RANGE. WHILE ANTICIPATED COVERAGE IN THIS AREA
REMAINS TOO LOW FOR INCLUSION IN A THUNDER OUTLOOK AT THIS
TIME...ANY STRIKES WILL BE CAPABLE OF IGNITING NEW FIRES...AS FUELS
REMAIN DRY.

...SYNOPSIS...
...PORTIONS OF THE GREAT BASIN TO THE SIERRA MOUNTAINS...

MIDLEVEL MOISTURE WILL SLOWLY INCREASE NORTHWARD ACROSS PARTS OF THE
WESTERN GREAT BASIN BENEATH LARGER-SCALE UPPER ANTICYCLONE CENTERED
OVER NORTHERN AZ. WEAK IMPULSES MIGRATING THROUGH UPPER FLOW WILL BE
SUFFICIENT TO TRIGGER ISOLATED THUNDERSTORMS. PW VALUES WILL BE
LOW...GENERALLY LESS THAN 0.75 INCHES. WEAK DEEP LAYER FLOW WILL
RESULT IN SLOW STORM MOTION...BUT INVERTED-V SUB-CLOUD THERMODYNAMIC
PROFILES WILL LIMIT WETTING RAINS. GIVEN VERY DRY FUELS ACROSS THE
REGION...THUNDERSTORMS WILL POSE A RISK FOR LIGHTNING IGNITIONS.
