With summer-like temperatures covering the Treasure Valley like a warm blanket today, a yellow air-quality alert for increased ozone levels has been issued for Boise. The AQI index for today is 53, on the low end of the moderate level.

Temperatures are expected to hit the upper 80s today, with continued warm days and clear evenings through much of the week and not a chance of showers expected until Friday.

Meanwhile, the Boise River continues to run high - at approximately 7,300 cubic feet per second. The flood flow is 7,000 cfs. Regulated flows on the river below Lucky Peak Dam will continue run above flood stage, but if the dry weather continues as exected, flows will likely be reduced slowly by the U.S. Bureau of Reclamation and U.S. Army Corps of Engineers.

Don't get too used to high temperatures near 90 degrees. A change is coming. In fact, the National Weather Service Office in Boise has indicated that strong thunderstorms with winds gusting as high as 50 mph will sweep through the region this afternoon and last through the night.

The wind will push through showers and thunderstorms through much of the week, and by week's end, temperatures will drop nearly 30 degrees.

Idaho appears to be in good shape when is comes to water heading into summer. The Idaho Water Supply Committee huddled Thursday and confirmed that record-setting snow and rain storms in March saturated much of central and northern Idaho, with precipitation measured at 200-300 percent above normal in some areas.

"Even if we didn't get any more precipitation, we should have an adequate water supply across the state," said Jay Breidenbach, senior hydrologist with the National Weather Service office in Boise.

Three consecutive years of robust snowfall and spring rain have adequately dampened doubts about a drought anytime soon.

"I think everybody is pretty excited that there should be no water shortages," said Breidenbach. "Statewide, I would say the water supply is in great shape."

While Boise enjoys a taste of spring today, with temperatures hovering around 60, and a hint of summer Sunday (temperatures are expected to be in the high 70s and possibly 80 degrees by Monday) eastern Idaho was reminded this morning that winter hasn't exactly vanished.

ABC News this morning showed pictures of nearly a half-foot of snow blanketing Idaho Falls.

The National Weather Service in Boise is forecasting pleasant weather for the next several days for the Treasure Valley.

Meanwhile, the Boise River continues to inch higher. As of 6 a.m. this morning, the Boise River was at 9.87 feet, with a flood stage of 10.1 feet.

How much rain has fallen in the Pacific Northwest? Consider this: It's the second-wettest March ever for Portland, and Seattle is on track for its third-wettest March. We're talking about Portland and Seattle, people.

The National Weather Service is calling for more showers through the weekend, with a good chance of the rain turning to snow early Sunday. The forecast should yield a bit of sunshine on Monday, but the rain is expected to return by next Wednesday, continuing again into next weekend.

In Western Idaho, weather watchers are keeping a close eye on the Weiser River in Washington County. The heavy rain and snow melt has produced a flood warning until this evening. The flood stage is 9.5 feet, and early this morning, the Weiser River was running at 8.9 feet.

Warmer temperatures and more precipitation in the forecast have law enforcement keeping a close eye on the Boise River. Already, two sections of the Greenbelt in Southeast Boise have been closed by high water.

Temporary closures include the Bethine Church River Trail from the Cottonwood Apartments east to Bown Crossing, and Loggers Creek Bridge from Leadville Avenue east past the West Parkcenter Bridge.

As of late Saturday, the Boise River was running over 9.2 feet, with a flood stage of 10 feet.

The National Weather Service office in Boise is calling for more showers likely after midnight in the Treasure Valley, continuing into Monday morning. A small stream flood advisory is in effect for parts of Blaine County in central Idaho, including the communities of Bellevue and Carey.

Anyone still doubting climate change simply isn't paying attention.

In spite of very little snow dropping on the Lower 48 this year, the Associated Press reported that the city of Anchorage, Alaska, has tried pushing more than 250,000 tons of snow away from its city streets (and yes, that's quickly approaching a record amount).

The National Weather Service has reported that the first three months of 2012 have seen twice the normal number of tornadoes. Nationwide, there have been 132 tornadoes confirmed in January and February, with preliminary reports of more than 150 already in March.

So far, the month of March has seen 1,757 new high-temperature records in cities across the nation. Last Thursday alone, 36 states set daily high temperatures.

Highway 55 near McCall was back open to two lanes Sunday but law enforcement is keeping a close eye on the weather. A solid week of heavy rain flooded miles of farmland in Boise and Valley counties, spilling onto the roadway and forcing authorities to close down stretches of the north-south thoroughfare.

Meanwhile, sandbags remain in place along streets and outside of homes and businesses in the Adams County community of New Meadows.

The National Weather Service has posted a hazardous weather outlook for southwest and west-central Idaho. Winter driving conditions have been reported near mountains and foothills above 3,000 feet.

In the Treasure Valley, more than one-third of an inch of rain fell Saturday and all eyes are on the Boise River, which was running a 8.13 feet Sunday morning. Flood stage is 10 feet.

• Boise River spills over some banks near Boise's Ann Morrison Park.

A trough of steady precipitation remained over south-central Idaho early Saturday, which is bad news for already water-logged Adams and Valley counties.

The village of New Meadows declared a flood emergency on Friday and set up an evacuation respite in the town's senior center. Sandbags line several neighborhood streets but floodwaters cover many of New Meadows' thoroughfares.

The McCall Star News reported Friday that several major roads, including stretches of Highway 55 such as the "S" curves between the Rainbow Bridge and Round Valley, were covered with water. A pilot car was being used to guide one lane of traffic through the area.

Meanwhile, the Brundage and Tamarack ski resorts are enjoying some of the best snowfall of a challenged season. Brundage announced this week that it hoped to remain open weekends into early May.

The National Weather Service has issued a flood watch in effect for lower rivers throughout the Treasure Valley and a winter storm warning for the Sawtooth Mountains and Big and Little Wood River areas.

Nothing is guaranteed, but operators at Bogus Basin and Brundage ski resorts were a bit more confident this morning that they'll be opening sooner than later, following the recent snowfall.

Bogus operators were cautiously optimistic on Facebook: "Woo-hoo! We'll take it!" they wrote. "There are more storms on the way!"

Brundage operators wrote this morning on the resort's Facebook page that "there is a strong chance" that slopes would be open north of McCall beginning Friday, Jan. 6. As of this morning, the mountain was already partially covered with a base ranging from 12-18 inches. Brundage celebrates its 50th birthday Wednesday night with a "Light Up the Night" event, featuring a bonfire, live music and fireworks.

The Boise office of the National Weather Service said more precipitation was likely for the remainder of the week (rain in the valleys, snow in the mountains) with a strong trough of precipitation continuing to push in from the Pacific.
