Hurricane Marie, currently positioned far to our south, is projected to travel west and well out to sea, with no direct impacts expected. However, mid-level tropical moisture associated with Hurricane Marie is forecast to interact with the large upper level trough over the West Coast this weekend. Computer forecast models are increasingly in agreement on rainfall chances across the region, although rainfall amounts still vary considerably. According to the National Weather Service, ensemble means are currently showing precipitation amounts between 0.2-0.3 inches across the valleys, with higher totals for the coastal slopes and mountains. Due to uncertainty regarding the exact placement of the large upper low, rainfall amounts from this syste ... http://weathercurrents.com/murrieta//NewsItemDisplay.do?Id=1686 The recent stretch of exceptionally hot days across Southern California, has been exacerbated by modest humidity and high dew points - a rather uncommon combination for the region. Widespread high temperatures in the upper 90s and 100s across the inland valleys since roughly August 19, were compounded with unusually high heat index readings (Heat Index being a calculation that translates air temperature readings into what the conditions currently "feel like" to humans). Inland, heat index values exceeding 110 degrees were observed nearly every afternoon over the past week - brought on by unusually warm SSTs (Sea Surface Temperatures) off the Southern California coast, which contributed to relatively high humidity and high dew points during what was already a significant heat wave baking the region during the hottest time of the year. Dew points were unusually high along and near the coasts, frequently in the 70s, compared to more typical dew points in the 40s and 50s. Dew points ... http://weathercurrents.com/murrieta//NewsItemDisplay.do?Id=1685 The Extreme Heat Watch previously issued by the National Weather Service for a large portion of Southern California from 10 AM Tuesday until 8 PM Friday, has been upgraded to an Extreme Heat Warning covering the same timeframe. The difference between both advisories is mainly due to the increased heat threat, with temperatures in areas under the Extreme Heat Warning now forecast to reach up to 110 degrees during the peak of the heat wave. In addition, this also raises the risk for heat-related illnesses across affected populations. Very warm nights, with low temperatures significantly above average, will provide little to no relief from the excessive daytime heat. The Heat Advisory currently in effect across much of the region, will remain in place until 10 AM Tuesday with no changes. As a reminder, the National Weather Service cautions the public to drink plenty of fluids, stay out of the sun and in an air-conditioned room if/when possible, and check up on relatives and neighbors. http://weathercurrents.com/murrieta//NewsItemDisplay.do?Id=1684 A strong ridge of high pressure over the Four Corners region is slated to bring dangerous heat to Southern California later this week, prompting the National Weather Service to issue both a Heat Advisory and Extreme Heat Watch this week. Inland valleys baked in widespread triple-digit heat this weekend, with nearly every active WeatherCurrents station soaring past the century mark Sunday afternoon. Lake Elsinore was once again the hottest location in the WeatherCurrents lineup, with a high temperature of 112 degrees recorded there on Sunday. The current Heat Advisory in effect for areas away from the immediate coast, all the way to (and including) the mountains, is set to expire at 10 AM Tuesday morning. From that time, an Extreme Heat Watch will go into effect from Tuesday morning and last until Friday evening - and will affect not only the inland valleys, but also the mountains, high desert and even the immediate coasts(!). During this period, temperatures between 90 and 100 de ... http://weathercurrents.com/murrieta//NewsItemDisplay.do?Id=1683 A heat advisory issued by the National Weather Service for the interior valleys of Southern California, is set to expire at 8 PM Thursday evening. Temperatures soared again Wednesday across the region, with eight out of eleven active WeatherCurrents stations reaching or exceeding 100 degrees Wednesday afternoon. Lake Elsinore topped out at 112 degrees, the hottest temperature in the WeatherCurrents network for Wednesday. Most other stations in the network recorded high temperatures between 100 and 106 degrees, while WeatherCurrents stations in Fallbrook, Simi Valley and Pinon Hills only remaining slightly less hot. Across the San Bernardino and Riverside County valleys, high temperatures similar to Wednesday's are forecast again for Thursday. The deserts, mainly east of the San Jacinto Mountains (including eastern San Bernardino County) remain under an extreme heat warning through 8 PM Friday. Monsoonal moisture is forecast to increase during Thursday and Friday, raising chances ...
