Carson City area weather: Temperatures to reach near record highs by weekend prompting flood concerns
A warmup through the end of the week into the weekend will result in near-record to record high temperatures across the Sierra, Carson City area and western Nevada, according to the National Weather Service. Forecasters say the heat will increase the probability of some flooding due to snowmelt.
The warmest temperatures so far this spring are expected to arrive this weekend, with afternoon highs up to 20 degrees above-average for late April. By Saturday, mid-to-upper 80s are expected across much of western Nevada, with 90 degrees not out of the question for portions of the Basin and Range. The weather service advises that If recreating or spending time outdoors, be aware that it will be unusually hot for this time of year and prepare accordingly.
These warm temperatures, along with mild overnight lows, will likely result in efficient melting of snowpack. Consequently, high river flows are anticipated across much of the region. Water will be swift moving and very cold, so be cautious if approaching a river bank. With snowmelt-driven river rises, daily fluctuations are common and it is possible the peak flows will occur overnight. Keep this in mind when setting up camp near the water, according to the weather service.
A Flood Watch for the snow melt has been issued by the NWS Thursday through Monday, for the following areas: In western Nevada, Greater Lake Tahoe Area, Greater Reno, Carson City, Minden Area and Mineral and Southern Lyon counties. Elsewhere, portions of California and western Nevada, including the following areas, in California, Greater Lake Tahoe Area, Lassen-Eastern Plumas-Eastern Sierra counties, Mono County and Surprise Valley, Calif.
National Weather Service Forecasters say creeks and streams will be running high and fast and that low-water crossings may be flooded. Minor mainstem flooding is currently forecast along the Forks of the Carson River beginning late Friday.
The Susan and Walker rivers will also need to be closely monitored as flooding cannot be ruled out. Anyone participating in outdoor recreation this weekend should use caution as water will be running high, fast, and potentially out of banks for some creeks and streams. The weather service warns water will be extremely cold and exposure could cause shock.
Looking ahead, a return to cooler, more unsettled weather with the chance of mountain snow showers and valley rain and/or thunderstorms will be possible much of next week. Stay tuned to the forecast for updates on this early May pattern change.
