SOUTH LAKE TAHOE, Calif. – A warming and drying trend is expected this week in the region with hot conditions returning late week into the weekend, according to the National Weather Service (NWS) in Reno.
Late in the week, NWS Reno says there is an opportunity to meet the record for South Lake Tahoe. The record for Friday at South Lake stands at 90 degrees, the forecasted high temperature. Reno-Tahoe Intl Airport has a record for Friday, standing at 101 degrees, with a forecasted high of 99 degrees, so this record seems pretty safe in contrast. Of course, signals in the blended guidance may fluctuate as the end of the week draws nearer, but little variance is expected.
Showers and storms return to the Sierra and Sierra Front south of US-50 for Thursday. The flow will be related to the position of the Four Corners high-pressure dome. The showers will develop along the periphery of the high pressure, with southerly flow tapping into the subtropical jet and monsoonal moisture sources. The setup will be one to watch, since the shower development is tied to the location of high pressure. A westward shift of 50 to 100 miles could keep us hotter and drier, while a favorable placement would have the edge of a high-pressure line up along the Sierra, says NWS Reno. This scenario would produce more showers and storms with chances for wetting rains. Friday through Sunday, the current forecast calls for shower
chances to become greater and more widespread. Keep an eye on things as we go through the week.
