Enjoying a gorgeous Memorial Holiday with near-normal temperatures and dry conditions. A weak low-pressure system will slide inland to our north this week, ramping up the onshore flow with gusty west winds, cooler temperatures, and a chance of showers. Expect mostly sunny skies out there today with highs in the upper 60s to around 70°, southwest winds 5-15 mph with gusts near 20 mph during the afternoon. Some mid-level moisture will bring us a few afternoon clouds, but merely fair weather cumulus; no thunderstorm activity is anticipated. As the onshore flow strengthens, the marine layer will deepen enough for light rain and drizzle across the coastal and valley areas over the next few days, mainly late night and early morning hours. This moisture will bank up against the lower coastal slopes and could spill into the Big Bear Valley, especially Wednesday night or Thursday morning. This may generate a few light showers or flurries across our area. Highs will cool to the mid-60s on Tuesday, dropping into the 50s on Wednesday and Thursday, while overnight lows generally cool to the 30s, but could dip into the upper 20s on Wednesday night. High pressure will settle back over the region by the end of the week, bringing a nice warm-up through next weekend. Also monitoring an early intrusion of monsoon-type moisture to our east, which has brought thunderstorms to much of Arizona and New Mexico. For the time being, this moisture will remain east of us, but could be drawn a little further to the west during the first week of June.
