We have another complex forecast in store today with temperatures and rain chances. The only thing that will not be complex to forecast is the extensive cloud cover; we'll be cloudy all day today. The passage of yesterday's cold front has placed us in the cold sector, but warm air advection, isentropic lift, and positive vorticity advection will all contribute to a chance of rain today. That being said, the best lifting appears to be to our north and I think that will be where the steady, moderate rain will occur. However, we may have to contend with a few showers at times today so it wouldn't be a bad idea to carry an umbrella with you to work or school. With temperatures currently running in the mid 40s, I don't think we will see a lot of change in temperatures throughout the day. In fact, we may hold steady in the mid 40s for most of the morning and afternoon. I'll forecast a high of 46 this afternoon, but again, there likely won't be much change in the temperature today.
Overnight, the lifting in our area will increase and rain chances will be quite high tonight and into Friday morning. The temperature may slightly rise after midnight and we could be near 47 tomorrow morning. The end of the work week looks absolutely wet with over 3" of rain possible tomorrow!
