Weather

***Much Warmer Next Week***

Gusty north and northwest winds will continue in a few areas this morning in the wake of the cold front which moved through the area yesterday.  Winds of 25-35 mph with gusts to 45 mph will occur through noon in the Tehachapi Mountains, the I-5 Corridor and in the Antelope Valley, before winds slacken during the early afternoon hours.  Temperatures will be a few degrees warmer today due to abundant late-April sunshine and hghs will reach the 70s at lower elevations and the 50s in the mountains.  Expect temperatures to be 5-8 degrees warmer Thursday due to a weak ridge passing through the area.  On Friday, an unseasonably cold storm system is expected to enter the Pacific Northwest with the tail end of the system reaching the central part of the state.   This will lead to some light showers for Central California, mainly in and near the Sierras.  Up to a half inch of rain may fall in the Sierras north of the Sequoia National Park with lesser amounts over the coastal ranges and other higher terrain.  Some light showers bringing a trace to a tenth of an inch will be possible across the mountains of Southern California Friday evening.  Strong west and southwest winds of 25-35 mph with gusts to 45 mph will return to the deserts with the strongest winds occurring near the Nevada border.  All winds should end late Friday night.  Temperatures Friday and Saturday will be much cooler with highs only reaching the 60s in the lower elevation and 40s in the mountains.  However, a strong warming trend is expected early next week as a high amplitude ridge of high pressure builds over the Great Basin.  By Monday and Tuesday, high temperatures will be well into the 90s in the valleys and foothills and daytime RH will likely fall into the teens.  Some light offshore flow may occur Tuesday night and Wednesday.  The very warm and dry weather may last through next Wednesday before cooler weather possibly returns for the first weekend of May.

Fuels/Fire Potential

Large fire potential will generally be low through the end of the week due to cool temperatures and relatively green fine fuels.  But next week's hot and dry weather should promote rapid drying and curing of seasonal grasses at lower elevations.  Grasses should show strong visual cues of drying across most of the exposed south aspects in Southern California, but some shaded areas and understory grasses will likely remain green through the upcoming heat wave.  There may be a significant increase in grass fires next week as these fuels become much more receptive to ignition, especially across the urban interface areas and foothills.  Some light rain may occur Friday and again toward the end of next week, but sustained, soil-penetrating rains are probably done for the season.  Expect light IA through Saturday, then moderate IA for the first half of next week.
