US Weather Spotlight: 5-10-19

A frontal boundary is draped from southern TX northeastward into the eastern Great Lakes to begin today, and this feature will be the focal point for storm activity through the weekend. Heavy rain is possible with these storms with widespread 1-3 inch total rainfall possible for much of the eastern third of the country through the weekend and even higher amounts of 5 or more possible in southeast TX, LA, and southern MS. What will eventually get this front moving eastward will be a low pressure system building in from Canada into the northern Plains tonight, Midwest Saturday night, and the eastern Great Lakes by Sunday night. This system will produce a few showers in these regions but the majority of this should be fairly light. 

A cut off low pressure system will affect the southwestern US through the weekend with scattered showers and a few storms. Some of the rain with this activity could be heavy at times especially in the San Joaquin Valley in CA, southern NV, northern AZ, southeast CO and NM.

The best weather region goes to the Pacific Northwest where dry conditions and above average highs are expected through the weekend.
