.DISCUSSION... (This afternoon through next Sunday)
WEATHER PATTERN OVERVIEW: Increasing cloud coverage with increasing chances for showers and isolated thunderstorms this afternoon as remnants of a tropical storm pushes moisture back into the silver state. The weather is expected to dissipate by the evening, leaving calmer conditions overnight with lows in the 40s to 50s.
Monday, a stronger and wetter weather system will move into northern and central Nevada, expecting to last through Tuesday. Chances for isolated rain showers range from 50-90% with the highest chances across northern Nevada and along the I-80 corridor. The storm front will also bring in cooler temperatures with highs in the 70s Monday, dropping into the 60s to low 70s by Tuesday. Overnight lows remain in the 40s to 50s.
By mid-week, drier conditions return, giving a break to the ongoing weather with a southwesterly flow and slightly warmer temperatures but stay in the upper 60s to 70s. A low pressure system off the northwest coast may bring additional light showers across northern Nevada each afternoon. By the end of the week, more unsettling weather may continue, however there is low confidence on the strength and position of the system at this time.
FORECAST CONFIDENCE & DEVIATIONS: Moderate to high confidence of isolated showers and thunderstorms this afternoon, lasting through Tuesday. No changes have been made to the grids at this time.
