Another system is slated develop late in the week on the parameter of this "polar air mass" and shoot thru the Lower Great Lakes. Interesting and also ironic; as winter snow buffs were looking for some sort of semblance to this type of system back in the cold season. This low on the models has been showing many preliminary characteristics of a winter-type low pressure for development and track thru the region late in the week. While temperatures will be cool; no winter type precipitation is expected. I will update about this system as it plays out on guidance, also.
Much of the southern half of Southeast Lower Michigan could use the hopeful rain as it has been rather dry; NOT a good time in the growing season for fellow gardeners and farmers. Check out these precipitation stats for Detroit, Flint and Saginaw for the spring and May thru the 27th:
MAY TO DATE 1.34 NORM 2.93 -1.59 LAST MAY 5.13
SINCE MAR 1 6.44 NORM 8.11 -1.67 LAST SPRING 14.35
MAY TO DATE 6.87 NORM 2.68 +4.19 LAST MAY 6.90
SINCE MAR 1 10.23 NORM 7.48 +2.75 LAST SPRING 16.29
Ironically; last May and this May are neck in neck for rainfall at Flint but even with the earlier flooding rains this May, it is nowhere close to last spring's total rainfall to date /16.29/!
The Saginaw Valley region was drier but heavy rains trekking southeast across the region Sunday put an end to that; and the area is now on par to be closer to normal for rainfall both May and spring.
PRECIPITATION: MAY.... 3.62 SPRING.... 7.30
As mentioned; we are still expecting scattered showers and storms overnight into Tuesday morning, then a slight chance Wednesday. So these totals are likely to change.
Making weather fun while we all learn,
