Good Saturday morning! Morning radar remains rather inactive with plentiful sunshine being observed across the vast majority of the region.
Upper-level cirrus clouds over the last several hours have quickly pushed into western ND where a majority of the storm chances will exist this afternoon and evening. A cold front will push into the western Dakotas this afternoon providing enough lift given the instability in the region to initiate scattered storm development from northwest SD to north-central ND between 2-4pm CDT. Over the course of the evening these storms will push east before weakening and dissipating shortly after sunset due to less instability in the eastern Dakotas and a lack of daytime heating. Additional development of showers and storms are expected early Sunday morning (~2-3am CDT) across the western and central portions of SD where the frontal boundary will be positioned at that time. These storms will also push east Sunday morning before eventually hitting a wall in east-central SD where the environment remains less conducive. A few isolated showers and storms are possible in eastern SD into central MN late Sunday morning into early afternoon, however.
The SPC has highlighted central ND for the possibility of a few strong to severe thunderstorms along the broken line of storms this afternoon and evening. The main threats with these storms include large hail and a few severe wind gusts. An isolated tornado cannot be ruled out across far north-central ND.
Total rainfall through 7pm CDT Sunday depicts scattered rains from north-central ND southward into central/western SD. In general a tenth to half an inch of rain is possible in these areas with locally higher amounts possible. Many locations across central ND will miss out on rains as the storms this afternoon and evening will likely be more discrete in nature.
Here’s a look at the progression of temperatures over the next four days: High temperatures will be elevated today (low to mid 90s) across the western Dakotas before the cold front comes through Sunday knocking down temperatures behind it. A more seasonable air mass will position itself across the region Sunday through Tuesday.
Here’s a look at dew points over the next four days: Dew points will drop drastically beginning Sunday across ND and northwestern MN/SD before pushing into the majority of the region Monday. Comfortable humidity levels will remain in place across ND and MN Tuesday.
