Week Weather Outlook- Sunday PM
Latest surface data suggests that the frontal boundary moving through is beginning to trigger showers and thunderstorms this evening. The models didn't show this.
The GFS and WRF-NAM have been showing a frontal boundary to slip to our south on Monday, and then waves of low pressure will form along this boundary, probably getting kicked back as a warm front Monday night.
We'll likely have some heavy thunderstorms Monday evening into night and there's some suggestion that showers and thunderstorms will be around much of Tuesday. (The NAM has thunderstorms late afternoon on Monday.)
Timing this sort of situation is difficult, but expect some soggy conditions on and off for the next several days.
