...Flash Flood Watches for portions of Arizona, New Mexico and Texas...
...Frost Advisories and Freeze Warnings for the Upper Great Lakes and
northern New England...
Early this morning, remnant tropical moisture and energy from 'Odile' was
slowly migrating away from southeast Arizona and spreading eastward into
southern New Mexico and southwestern Texas---with heavy rainfall expected
to continue into Thursday night.
The heaviest rainfalls are expected to spread downstream into east central
New Mexico, the Texas Panhandle, and central and south central
Texas---with widespread 1-2 inch amounts over the next 24 to 48 hours.
Isolated 3-4 inch rains are possible within the WPC excessive rainfall
threat areas...extending from Tucson AZ to Silver City NM and generally
arcing east-southeastward across a sizable portion of central Texas---from
Abilene to Austin and the Houston metro area. Even though 'Odile' will
dissipate within 24 hours, its moisture will linger over the southern
Plains and southern Rockies into Friday night.
In northeast Minnesota, northwest Wisconsin and the entire Upper Peninsula
of Michigan---frost and/or a hard freeze is likely before sunrise. The
cold temperatures move downstream into southeast Canada and northern New
England tonight---with frost and/or a hard freeze expected tonight and
early Friday morning for much of upstate New York, northern New Hampshire,
and all of Vermont.
