Nice and Cool Next Week

Temperatures were able to get a little warmer today in the upper 70°s to low 80°s, the reason being that we have a low pressure system out to our west, which has been pulling in warmth and moisture to our area.  This allowed for some cloudier conditions today, but we still got to see plenty of sunshine.  That low pressure influence is closing in on our area while the low center tracks southeast, which is why clouds will continue increasing through the evening and overnight.

The resulting moisture inflow will keep the clouds in our area through tomorrow, and also bring us a slight chance for some light rain showers.  The warm front will stay well to our south, but with how much moisture is moving in, we could see a couple of pop up showers tomorrow morning down in Whiteside, Lee, and the southern portion of Dekalb county; and then everywhere else going into the afternoon due to daytime heating.  The overall rain chance is low, as couple pop up light rain showers are possible.

Luckily, the rain chance decreases as we head through the afternoon as that low pressure system will move southeastward with the flow of the jet stream.  However, we'll still hang on to the cloud cover through Sunday night.  The clouds will clear out Monday mid-day when a strong high pressure system moves in from Canada.  This will push the jet stream south, thus keeping that low pressure system south, and bring us dry and cool weather for most of the work week.  We'll see temperatures in the low to mid 70°s during the week, but the dry influence will keep the skies clear, so we'll have plenty of sunshine to go along with the 70°s.

That high pressure system moves out late Friday night, allowing a weak low to move in Saturday morning and bring us a chance for some light rain.
