Sunshine and partly cloudy skies will help temperatures reach the upper 40’s today as the high pressure system in the Great Lakes region continues to push eastward. Look for clouds to increase as the day progresses and conditions to become progressively worse from Saturday night on. Winds will shift to a southwesterly flow later today followed by a small disturbance pushing through tonight and with it a small scattered amount of precipitation is expected. Southwesterly winds will greet Saturday and help temperatures rise above 50 degrees in the afternoon but cloudiness will vary across the region, so if the sun is able to peak out of the clouds for an extended period of time we could see temperatures reach the mid-50’s. Arctic air will push in from the northwest again later Saturday bringing the chance of light precipitation on Saturday night. As of now our region is in a Winter Storm Watch and could see significant ice and snow accumulations Sunday night into Monday. However, not much will be said about the upcoming event because forecast are still very uncertain. This potential winter weather maker is still off the coast of California, so it has not yet been sampled well enough for our Numerical Models. Current models now do a have a low pressure system tracking northeast from Texas to off the coast of the Carolinas. The QPF model shows a heavy amount of precipitation falling during this event, reaching above 2in, but sleet/snow/ice amounts will vary greatly depending on the thermodynamic set up as the system progresses through.
Into Monday morning as the system passes cold air from the north-northwest will cause any remaining precipitation to fall as snow but expect the atmosphere to dry out into Monday night. Again, I will not mention snow/ice fall totals right now but it would be a great idea to keep an eye on the system as Sunday approaches.
