Another great day today with no major weather problems ...My report runs 2  and a half minutes , Airline hub weather the the forecast for DC to Boston, centered on North Jersey and NYC. More details are below.One more round of moderate to locally heavy rainfall will sweep acrossCalifornia through tonight, reaching into the Desert Southwest onThursday...More higher-elevation heavy snow across the Intermountain West with awintry mix over the northern High Plains through tonight; mainly acrossthe Four Corners on Thursday...Temperatures will continue to run above average for the central/easternU.S. with record warmth over parts of the upper Midwest into the GreatLakes... As another energetic upper-level trough and associated frontal systemsreach the West Coast, another round of moderate to locally heavy rainfallcontinues to push onshore across northern and central California thisWednesday afternoon.  The heavy rain falling on top of the very wetantecedent conditions may still bring a risk for some isolated instancesof flooding, particularly along coastal central and southern Californiathrough tonight and remaining along the Mogollon Rim of Arizona throughThursday.  Higher elevations of the Sierra Nevada andTransverse/Peninsular Ranges will see some additional heavy snowfalltotals of around 6-12", while the Cascades and northern Coastal Ranges ofCalifornia will see some light to moderate snowfall.Meanwhile, a low pressure system that has been developing over the centralHigh Plains will track northeastward across the northern Plains throughtonight before crossing the upper Midwest on Thursday.  Moistsoutheasterly flow overriding colder air along and east of the Rockieswill bring an expanding area of snow across the northern Plains throughThursday before tapering off over the upper Midwest on Friday as the lowpressure system moves away toward James Bay, Canada.  Most locationsacross the northern Plains should receive 6 inches or less of snow fromthis system.  However, some snow bands could deliver heavier snowfall ofup to a foot over portions of Montana.Between the system moving into California and the developing low pressuresystem over the High Plains, widespread snowfall can be expected acrossthe Intermountain West through tonight.  Regional mountain ranges such asthe Wasatch and central Arizona will receive heavy snow, where additionalsnowfall over the next two days will generally range between 10-20", withtotals over 2 feet possible.  Higher elevations of the northern Rockiesand central Great Basin will generally see between 4-8 inches, with somelocally higher amounts.  Lower elevations/valleys will see a mix of lightto moderate rain and snow showers, though any snow accumulations shouldremain limited.  Precipiation chances should trend downward on Thursdayand into Friday as the system finishes traversing the southern Rockies andbegins organizing a new low pressure system over the south-central HighPlains on Friday with scattered showers and some thunderstorms developingover the Mid-South.High temperatures will remain above average broadly across central/easternportions of the country, with much above average conditions centered onthe Upper Midwest and Great Lakes, where forecast highs in the 40s, 50s,and even some low 60s are upwards of 25-35 degrees above average. Somerecord-tying/breaking high temperatures are possible. Otherwise, highswill generally range in the 30s and 40s for New England, 40s and 50s forthe Mid-Atlantic/Carolinas, 50s and 60s for the Ohio Valley/Southeast andcentral Plains, and 60s and 70s for the southern Plains. Highs will remainbelow average in the West under the influence of the upper-level trough
