Mesoscale Discussion 0065 NWS Storm Prediction Center Norman OK 0318 PM CST Sun Feb 03 2019 Areas affected...Sierra Mountains Concerning...Heavy snow Valid 032118Z - 040315Z SUMMARY...Heavy snow, with rates of 1 inch per hour and locally exceeding 3 inches per hour at times -- especially at higher elevations, will develop into the evening. DISCUSSION...Strong, moist flow into a cooling troposphere is supporting efficient snow production across much of the Sierra Mountains. This large-scale pattern is expected to remain in place through the evening as strong deep-layer ascent increases in response to the next cyclone moving southward along the California coast. Increasing ascent is already evident on water-vapor and infrared satellite imagery, as well as in radar imagery, across the Sacramento Valley as cloud tops have cooled and banded/cellular echos have developed. As the lower troposphere cools, snow levels fall, and these cellular features move into the Sierras, snowfall rates briefly approaching 3 inches per hour may occur at elevations as low as 6000-7000 feet. Strong winds will accompany this heavy snow resulting in blizzard conditions at times. Although snow will continue well into the overnight snowfall rates may relax a bit overnight before picking up in intensity again tomorrow ahead of the next short-wave trough embedded within the larger-scale trough. ..Marsh.. 02/03/2019 ...Please see www.spc.noaa.gov for graphic product...

…DENSE FOG ADVISORY REMAINS IN EFFECT UNTIL NOON CST TODAY… * VISIBILITY…Widespread fog producing visibilities of one- quarter of a mile or less will be common through midday. * IMPACTS…Poor visibility will create hazardous driving conditions.
…DENSE FOG ADVISORY IN EFFECT UNTIL NOON CST TODAY… The National Weather Service in Topeka has issued a Dense Fog Advisory, which is in effect until noon CST today. * VISIBILITY…Widespread fog producing visibilities of one- quarter of a mile or less will continue to expand across the area through the morning and continue through midday.
Mesoscale Discussion 0061 NWS Storm Prediction Center Norman OK 1010 AM CST Wed Jan 30 2019 Areas affected...Eastern Pennsylvania into southeastern New York...New Jersey and adjacent portions of the northern Mid Atlantic and southern New England Concerning...Heavy snow Valid 301610Z - 302015Z SUMMARY...A brief burst of heavy snow, strong wind gusts and reduced visibilities may accompany the passage of a cold front this afternoon, perhaps affecting much of the Greater New York City metropolitan area during the 2-4 PM EST time frame. DISCUSSION...The leading edge of stronger lower tropospheric cooling (centered around 850 mb...where temps falling from roughly -15 to -30C), now surging east of the Allegheny Mountains, is forecast to continue eastward into western New England and the northern Mid Atlantic region through 20-22Z. Model forecast soundings suggest that is being accompanied by increasing boundary layer destabilization supportive of deepening convective development, with tops likely to approach 10,000+ feet, particularly across parts of eastern Pennsylvania and central/northern New Jersey into southeastern New York late this afternoon. Frontogenetic forcing appears to be supporting a narrow, but sustained, evolving band of convection. This is likely being aided by lift within the exit region of a 110-130 kt cyclonic 500 mb jet streak forecast to nose across the northern Mid Atlantic, lower Hudson Valley, and southern New England by late this afternoon. Given the cold thermodynamic profiles, including a layer supportive of large dendritic ice crystal growth, guidance is suggestive that the convection may be accompanied by a burst of heavy snow rates around or in excess of 1 inch per hour. It appears this may last only 15 to 30 minutes at any one location, but it may be accompanied by fairly strong surface wind gusts in excess of 30 kts, and sharply reduced visibilities. ..Kerr.. 01/30/2019 ...Please see www.spc.noaa.gov for graphic product...
