Areas of low pressure riding along a slow-moving frontal boundary will keep us very unsettled for the majority of the work week. Mild and moist southwesterly airflow will keep plenty of clouds, fog and rounds of showers around into tonight. Rain will be especially widespread through 8:00 PM, then slowly become more scattered in nature through midnight. Heavier and more widespread rounds of rain look to begin to develop into early Tuesday morning. Temperatures overnight will hover in the mid-to-upper 40s, reaching the low 50s for most by tomorrow afternoon. We could have minor/localized flooding issues arise tonight and tomorrow, but a greater risk of high water will arrive later in the week.
After 10:00 AM Tuesday, we look to keep around of a lot of cloud cover, but rain should taper off for most of the afternoon and evening. We could see a few spotty rain/snow showers Tuesday night-early Wednesday, but most look to stay dry. Lows tomorrow night will fall into the 30s, and reach the mid to upper 40s again on Wednesday. More rounds of rainfall (heavy at times) look likely again Wednesday through Thursday. If there is the potential this week for wider-spread flooding and/or mudslides/rockslides, it will definitely be during this time-frame. Over the next several days, our area could receive anywhere from around 1.50" to 3 of rainfall in spots. With the ground already still soggy from last week, it might not take long to cause runoff issues over the next several days.
As the front moves out of the area Thursday night, the heaviest rain will end, but we could see a few light snow showers as cold air rushes in to end the work week. As of now, we are only expecting trace amounts of snow but SLICK AREAS DUE TO FLASH FREEZING/BLACK ICE will be a concern into Thursday night-Friday. Temps look to plummet into the 20s and teens Thursday night. Gusty winds behind the front could also cause tree damage & isolated power outages with the saturated ground. Stay tuned! Flood watches will likely be issued by the NWS in the coming days.
