Big Snow on the Big Island
Hawaii's highest peak could get up to another foot of snow Sunday, on top of the 2 feet that have fallen since Thursday, the National Weather Service says. A winter storm warning is in effect for the summits of Mauna Loa and Mauna Kea through Saturday evening. “Then we’re expecting another round on Sunday and Sunday night,” said Matthew Foster, a staff meteorologist with the National Weather Service in Honolulu. Snow on the peaks is not uncommon in the colder months of the year, though deep snow is rare. “We’ll probably see three to five snow events a year during the cold season. Some years we might not get any, some years we might get more,” said Foster. The only other area of Hawaii that gets snow with any regularity is the Haleakalā volcano on Maui, which at about 10,000 feet gets snow once every five years or so, he said."

Pacific Moisture Moves into the Pacific Northwest
Here's the Eastern Pacific precipitable water loop that shows heavier moisture from the Pacific moving into the West Coast in a few different waves. These rounds of heavier moisture have been responsible for heavier coastal rains and high elevation snow. Another one of these storms is moving through the Pacific Northwest now with heavier snow possible through early next week.
Another Surge of Heavier Pacific Moisture
Here's a look at the next storm system moving through the region through the early part of next week. Note that areas along the coast and in the lower elevations will likely see rain, while those in the higher elevations will see snow. Some spots could see 1ft to 2ft by early next week.
Winter Weather Headlines
...WINTER STORM WARNING IN EFFECT THRU 11 AM MST MONDAY... THE NATIONAL WEATHER SERVICE IN MISSOULA HAS ISSUED A WINTER STORM WARNING FOR HEAVY SNOW AND BLOWING SNOW...WHICH IS IN EFFECT FROM MIDNIGHT TONIGHT TO 11 AM MST MONDAY. THE WINTER STORM WATCH IS NO LONGER IN EFFECT. * IMPACTS/TIMING: SNOW WILL CONTINUE FOR TONIGHT AND SNOW INTENSITIES WILL INCREASE DURING THE DAY SUNDAY. THE COMBINATION OF ACCUMULATING SNOW AND WIND, VISIBILITY COULD BE GREATLY REDUCED, ESPECIALLY OVER MARIAS PASS. A PERIOD OF MODERATE TO HEAVY SNOW AND GUSTY WINDS IS LIKELY SUNDAY AFTERNOON AND EVENING WITH THE COLD FRONT. ALL OF THESE IMPACTS WILL CREATE HAZARDOUS TRAVEL CONDITIONS SUNDAY THROUGH THE FIRST PART OF MONDAY. * SNOW ACCUMULATIONS SUNDAY THROUGH MONDAY: 10 TO 14 INCHES WITH ISOLATED HIGHER AMOUNTS IN THE MOUNTAINS AND MARIAS PASS. * WINDS: GUSTY WEST NORTHWEST WINDS OF 30 TO 40 MILE PER HOUR POSSIBLE FOR MARIAS PASS.
Snow in the Northwest
Here's the snowfall potential through midday Tuesday, which shows fairly significant tallies across the Cascade range and across much of the northern Rockies. Some spots could see up to 1ft. to 2ft. through early next week.
According to NOAA's NOHRSC, 25.8% of the nation was covered up in snow as of December 3rd. Last year at this time, 33.4% of the nation was covered up by snow!
...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH SUNDAY EVENING... THE FLASH FLOOD WATCH CONTINUES FOR * PORTIONS OF SOUTHEAST TEXAS...INCLUDING THE FOLLOWING COUNTIES...JACKSON...AUSTIN...BRAZORIA...BRAZOS...BURLESON... CHAMBERS...COLORADO...FORT BEND...GALVESTON...GRIMES... HARRIS...HOUSTON...LIBERTY...MADISON...MATAGORDA... MONTGOMERY...POLK...SAN JACINTO...TRINITY...WALKER...WALLER... WASHINGTON AND WHARTON. * THROUGH SUNDAY EVENING * A SERIES OF UPPER LEVEL DISTURBANCES WILL PUSH THROUGH THE AREA TRIGGERING PERIODS OF RAIN WITH EMBEDDED STORMS. AS GROUNDS BECOME MORE SATURATED...THE THREAT OF FLASH FLOODING WILL PROGRESSIVELY INCREASE WHERE TRAINING HEAVIER CELLS MOVE OVER THE SAME AREA. EXCESSIVE RAINFALL HAS OCCURRED ALONG THE COAST ON SATURDAY...AND THAT WILL BE THE HIGHEST RISK LOCATION THROUGH SUNDAY MORNING. AN ADDITIONAL 2 TO 4 INCHES...WITH LOCALLY HIGHER AMOUNTS IN EXCESS OF 8 INCHES ARE POSSIBLE THROUGH MONDAY. WHERE GROUND IS ALREADY SATURATED IT IS MOST IMPORTANT TO FOCUS ON SHORT TERM RAINFALL RATES RATHER THAN TOTALS THEMSELVES.

Snow Depth Comparison 2016 vs 2015
Here's a look at the snow depth comparison from now to this time last year. Note that there is only a little snow left across parts of western and northern MN from the storm system a couple of weeks ago. Last year at this time, much of the state had a least a little bit of snow. The Twin Cites officially had 3" of snow on the ground as of December 2nd, 2015.
MN Snow Depth & Ranking
Here's a look at the snow depth across the state as of Thursday, December 1st. Note that much of the heavy snow that fell across western and northern MN a couple of weeks ago has since melted due to the ongoing mild weather through the end of November.
Each Thursday during the cold season, the State Climatology Office produces maps depicting the snow depth across Minnesota. Additionally, maps are created that depict snow depth ranking for the date. The data are provided by volunteers working with DNR Forestry, the National Weather Service, the University of Minnesota, Soil and Water Conservation Districts and CoCoRaHS.
3rd Wettest January - November on Record for the Twin Cities
Year to date precipitation through December 1st saw 38.18" of precipitation in the Twin Cities, which is 8.69". According to the Twin Cities NWS, the first 11 months of 2016 have been the 3rd wettest in history! Interestingly, Waseca set a new annual state precip record with 54.13" and the year isn't over yet!
Somewhat Active Pattern With Colder Temps Ahead.
Here's the weather outlook from Saturday to Saturday of next weekend. Note that we seem to have a few shots of light precipitation across the region with perhaps a better chance of snow next weekend. The big story will be the MUCH colder weather funneling into the region by the 2nd half of the week. This will be some of the coldest air of the season with highs dipping to well below normal temps for a several day period.
Slushy start for some on Sunday. Colder this week
It's been a strange year. Globally, we are well on our way to having the warmest year on record, which will beat the previous record set last year.
Regionally, the desert SouthEAST has been dealing with extreme and exceptional drought conditions, which was recently marked by the deadly fires near Gatlinburg, TN. Thank goodness more heavy rain is on the way this week as some of those areas still need 12 to 18 inches of rain to end the drought there.
Locally, the Twin Cities has seen its 3rd wettest 11 month period on record, running nearly 8.5 inches above average in the precipitation category since January 1st. Get this, as of November 30th, Waseca, MN has seen 54.13 inches of liquid, which is a new state annual precipitation record! Good grief.
Some wake up to a slushy coating Sunday as a quick moving clipper slides east. Temps warm to near 40 degrees on Monday with a few light rain showers late. Cold air breaks loose later this week with single digit wind chills for most.
Weather maps finally look like DecemBRRR!

Weather Outlook Sunday
High temps on Sunday will still be running above average levels with many locations warming into the 30s. A few locations across the southern part of the state may be close to 40F.
Weather Outlook Sunday
Winds will pick up just a little on Sunday as our weak system rolls through the region. Note that winds will be sustained up to near 10mph with gusts approaching 15mph to near 20mph across western MN.
Weather Outlook Sunday
As our weak system continues to move through the region on Sunday, a light/rain snow mix will begin to taper through the day.
Here's a look a the snowfall potential through PM Tuesday, which shows our slushy snow accumulations from PM Saturday into early Sunday. There will be another chance of light snow late Monday into Tuesday. The heaviest from the two weak systems will be found in northern Minnesota and into Wisconsin.
Extended Weather Outlook
The temperature outlook for Minneapolis into next weekend shows some big changes coming through the weather pipeline. Note the warming taking place through Monday, but a fairly significant whack of colder air settles in by the middle and end of next week with highs dipping into the 10s and 20s. Overnight lows will also dip into the single digits and 10s across much of the state.
6 to 10 Day Temperature Outlook
According to NOAA's CPC, the 6 to 10 day temperature outlook suggests colder than average temperatures settling into the region as we continue through the first part of December. Note that this will likely be some of the coldest air of the season for many spots across the Upper Midwest.
6 to 10 Day Temp Outlook
Here's the national temperature outlook from December 9th - December 13th, which shows a big chunk for colder than average temperatures settling into much of the nation. This will be one of the first big colder outbreaks of the season.... Are you ready!
National Weather Outlook
The weather looks to be fairly active across the southern US as we head through the weekend. A large blob of Gulf of Mexico moisture will begin settling into the South-central US with areas of heavy rainfall and scattered storms, some possibly strong to severe into early next week. Meanwhile, heavier moisture in the form of coastal rain and high elevation snow will move into the Pacific Northwest.
According to NOAA's WPC, the 5 day precipitation outlook suggests significant moisture across the southern US through the middle part of next week. Widespread 2" to 4" (isolated 3" to 6") can't be ruled out. This may lead to areas of flooding, but this additional heavy rain will be very beneficial for the drought conditions in the Southeast.
US Drought Monitor
Here's the updated drought monitor from Thursday, December 1st, which shows widespread extreme to exceptional drought conditions across much of the Southeast. While heavy rainfall last week helped some, we need more, so the upcoming heavy rainfall through the first full week of December (next week) is good news!
Rainfall Needed to End Drought
The product below suggests how much rainfall is needed to end the drought. Note that many spots need nearly a foot of rain or more to end the drought. These are the areas that are in an extreme to exceptional drought!
National Snowfall Outlook
Here's the potential snowfall through the the middle part of December, which shows the POTENTIAL of heavier snow developing across the northern tier of the nation over the next couple of weeks. This would be a big change from what we had during much of November as it was a generally quiet and warm month across the nation.
