.nother storm to bring additional heavy snows to northern Californiaand southern Oregon.A wet weather pattern for large areas to the east of the MississippiRiver.Much above average temperatures expected for much of the lower 48 to theeast of the Rockies over the next few days.Record high early morning lows possible from the Lower Lakes/OhioValley into the Northeast.An area of low pressure off the northern California/Pacific Northwestcoast will be moving slowly southeastward Tuesday and Wednesday to aposition off the central to southern California coast.  This storm will bespreading additional moderate to heavy precipitation amounts into northernCalifornia and southwestern Oregon over the next two days, with thepotential for additional snowfall totals of 1 to 2 feet from the southernOregon Cascades into the northern Sierra.  While these totals will be muchless than the previous more long lasting storm, travel will remaindifficult and the additional heavy snows will exacerbate recovery from thefirst storm.   Winter storm warnings are in effect for the northernSierra, northern California Coast Range and into southern Oregon foradditional heavy snow amounts.  The good news for this area of the countryis that after the next round of heavy snows, more tranquil weather isexpected for the remainder of the week.A wet weather pattern is in store for large areas of the lower 48 to theeast of the Mississippi River over the next few days.  This will be alongand to the east of a slow moving frontal boundary stretching southwest tonortheast from the Southern Plains into the Mid Mississippi Valley, OhioValley and into the Northeast and ahead of two areas of low pressuremoving from the central Gulf coast up along the east coast.    Moisturevalues expected to be much above average along and to the east of thisfront and ahead of the two areas of low pressure moving along the eastcoast, supporting the potential for widespread regions of precipitation. The heaviest rainfall totals expected from the central Gulf coast, acrossportions of the Southeast and Mid-Atlantic where the two areas of lowpressure are expected to move across.  The lead area of low pressure willspread rains across the Mid-Atlantic Monday night and into the Northeaston Tuesday.  This will be followed by another low moving from the centralGulf coast Tuesday night, into the Southeast Wednesday and theMid-Atlantic Wednesday night.  Rainfall totals of 1 to 2 inches possibleacross these regions, with isolated areas of flash flooding possible,especially in urbanized areas of the central Gulf coast. Much above average, spring like temperatures will persist for much of theweek for areas to the east of the Rockies.  Many areas will see hightemperatures Tuesday and Wednesday 15 to 25+ degrees above average.  Thewarmest temperatures are expected across the Southern Plains into theLower Mississippi Valley where widespread highs in the 70s and 80s areforecast. There are not expected to be any record high temperatures acrossthese areas over the few days, however, there is potential for widespreadrecord high morning low temperatures from the Lower Great Lakes into theNortheast where the above mentioned much above average moisture valueswill keep temperatures from cooling at night. Below to much below averagetemperatures are expected from the Northern High Plains, Northern Rockies,Pacific Northwest and northern California.  Across these regions, hightemperatures are expected to be approximately 10 to 20 degrees colder thanaverage on Tuesday and Wednesday.
