Saturday rain chance; cool and dry on Sunday

If your lawn or garden needs some rain, you could be in luck.

The steadiest rains Saturday morning have been over southeastern Minnesota, but there have been scattered showers and thunderstorms elsewhere.

A cold front will move slowly through Minnesota this afternoon and evening, and some additional showers and thunderstorms are expected.

The National Oceanic and Atmospheric Administration's North American Mesoscale forecast model shows the potential rain pattern Saturday afternoon through Saturday night:

It will probably rain in some spots that look dry on the simulated radar loop, but the loop illustrates the general rain pattern that is expected.

The color chart to the right of the loop refers to the strength of the signal that returns to the radar, not to the amount of rain.

Severe weather outlook

The Storm Prediction Center of the National Weather Service shows a marginal risk of severe weather Saturday and Saturday night for parts of eastern Minnesota, including the Twin Cities metro area, and western Wisconsin:

Marginal risk means that an isolated severe thunderstorm is possible.

Information on any severe weather that develops will be shared on the Minnesota Public Radio Network and on the MPR News live weather blog.

DISCUSSION AND 48-HOUR OUTLOOK

------------------------------

At 500 AM EDT (0900 UTC), the center of Hurricane Jose was located

near latitude 27.9 North, longitude 71.8 West. Jose is moving toward

the northwest near 9 mph (15 km/h). A turn toward the north with a

slight decrease in forward speed is expected later today.

Maximum sustained winds are near 80 mph (130 km/h) with higher

gusts. Jose could become a little stronger, and is expected to

remain a hurricane for the next several days.

Hurricane-force winds extend outward up to 35 miles (55 km) from the

center and tropical-storm-force winds extend outward up to 150 miles

(240 km).

The estimated minimum central pressure is 983 mb (29.03 inches).

 

HAZARDS AFFECTING LAND

----------------------

SURF: Swells generated by Jose are affecting Bermuda, the Bahamas,

the northern coasts of Hispaniola and Puerto Rico, and the southeast

coast of the United States, and will spread northward along the

Mid-Atlantic coast of the U.S. during the next few days. These

swells are likely to cause life-threatening surf and rip current

conditions. For more information, please consult products from your

local weather office.

 

NEXT ADVISORY

-------------

Next complete advisory at 1100 AM EDT.

Forecasters will be watching Hurricane Jose closely over the next few days.
