Above normal temperatures are on tap for the Aurora area this week. A more active pattern looks to take shape later this week and into next. The lack of significant snowfall will continue to break records through the week.
An upper level ridge has built across the eastern United States. This has pushed the jet stream north into Canada, trapping the cold air. Pacific air has made its way into the area, with temperatures reaching the lower 40's on Monday. High temperatures should remain in the lower 40's, if not a degree or two warmer on Tuesday. This is due to overnight highs staying up in the middle to upper 20's tonight.
The building upper ridge cut off an upper level low in Texas, as it separated from the northward retreating jet stream. This low will meander towards the region and should produce a healthy rain across the region on Thursday. There are also signs that another healthy precipitation event may be on the way on the weekend.
On Tuesday, a record will be tied for the longest stretch without seeing a calender day with a 1 inch snowfall at 319 days! This is according to National Weather Service statistics.
