SYNOP:
Dry today with light winds and slightly below average temperatures. East to southeast winds will increase on Monday ahead of a strong cold front which will bring the potential for heavy rain on Monday night. A moist onshore pattern will prevail behind the front this week with continued chances of precipitation and below average temperatures. Dry and warmer by next weekend as high pressure builds aloft.

WEATHER SUMMARY
It is looking like a stormy pattern will impact the region for the new week. The first Pacific storm system Monday-Tuesday will bring widespread rain and mountain snow. Precipitation amounts overall will be moderate.
Another storm system will affect the region Wednesday-Thursday with a greater potential for widespread heavy precipitation, but a higher level of forecast uncertainty due to the fact that the atmospheric river (aka pineapple express) may begin to weaken as it moves into our region.

CEDAR CITY Ut.
DAYS TWO THROUGH SEVEN…Sunday through Friday

Valley inversions will remain in place through at least Tuesday,with patchy fog and continued marginal air quality across most northern and western valleys including the Wasatch Front.

A series of storm systems will impact the outlook area during the middle to latter portion of the upcoming week, bringing periods of mountain snow and a mix of snow and rain in the valleys. At this time it appears likely that inversions will break midweek, while less certainty exists in the details of any rain or snow.

============================================================
THIS DAY IN WEATHER HISTORY:
2013: A cold and dry air mass produced a significant freeze in all areas away from the coast on 1/12 and on this day. Low temperatures dropped to the 30s near the coast, 20s inland and in the low deserts, and the low teens in the high desert, which caused some water pipe damage. A frigid -8 degrees was recorded at Big Bear City – Shay Meadows.
2009: The minimum temperature at Santa Ana of 73° not only set a record high minimum temperature for the date and month, but also for the entire winter season. Incredibly, the minimum is tied for the 23rd highest minimum temperature on record (and this was in January!). Persistent Santa Ana winds and strong high pressure were the causes.

2007: A trace of snow was reported in Rancho Bernardo, Escondido, Chula Vista, El Cajon and La Mesa. A cold snap settled over Southern California. Some remarkable records were set, particularly on this day and on 1/14. -7° at Fawnskin, -2° at Big Bear City and Wrightwood, 5° at Hesperia and Mt. Laguna, 10° at Borrego Airport, 12° at Campo, 16° at Ramona, 18° at Thermal, 19° in Hemet, 20° at Camp Pendleton. $114.7 million in crop damage in San Diego Co. $86 million in Riverside Co. $11.1 in San Bernardino Co. $600 thousand damage from broken pipes in San Bernardino Co. All three counties were declared disaster areas.

1997: A storm that started on 1/12 and ended on this day gave the coastal areas and valleys one to three inches of rainfall. Snow continued in the mountains and as of 1/15, 18 inches of snow had fallen at Mt. Laguna. Generally 18 inches to three feet of snow were reported above 2500 feet, but up to four feet accumulated in the San Gorgonio Wilderness Area. The ski resort at Snow Valley remained open until 5/18, the latest in its 78 year history. Dime size hail up to one foot deep covered a small area in Buena Park and Cypress. 13 illegal immigrants died from exposure near Pine Valley.

1993: A very wet series of storms that began on 1/6 and ended on 1/19 produced 20 to 50 inches of precipitation in the mountains and up to 12 inches at lower elevations over a two week period. This day marked the start of seven consecutive days (the most on record) of measurable precipitation in Victorville, which ended on 1/19. This also occurred on 2/18-2/24/2005, 2/14-2/20/1980, and 12/22-12/28/1971. Measurable rain fell nearly every day from 1/2 to 1/19 in San Diego County. Flooding and flash flooding, mud slides, etc., resulted.

1984: A tornado in Huntington Beach damaged a mobile home.

1963: The Western US chilled out more than usual when a massive arctic air mass descended on the region. The cold dry air mass filtered through the mountains into Southern California, helping Alpine (19°) and Vista (21°) set all-time record low temperatures.

1952: A series of storms brought heavy rain and mountain snow to the region starting this day and ending on 1/18. 5.52 inches fell in San Bernardino over the six days. Flooding was reported in Upland and Ontario. Heavy snow hit the San Bernardino Mountains with 40 inches in Lake Arrowhead (with a snow depth of 46 inches), and 37 inches in Big Bear Lake. All mountain roads were blocked and closed because of snow slides.

1949: 43 inches of snow fell at Palomar Mountain from 1/10 to this day, the greatest storm snowfall on record. On this day 20 inches fell, the greatest daily snowfall on record for January and the third greatest daily snowfall on record.

1882: A cold winter storm that started on 1/12 and ended on 1/14 brought lots of snow to the lowlands. 15 inches of snow fell at San Bernardino. 3 feet of snow fell in Campo over four days. Two to five inches fell in outlying San Diego, including four inches along Poway Grade, three inches at El Cajon and one inch in Poway. Light snow fell in Del Mar. Snowflakes fell, but did not stick at San Diego Lindbergh Field. Birds and livestock were killed and telegraph lines were knocked down.
