The ducks will be happy this week. You won’t want to go far from your Gortex as widespread rain will be pervasive Monday afternoon through Tuesday Night. A Flood Watch has been posted for that time frame due to the threat of moderate rain and snowmelt, not to mention that there are still areas of frost in the ground which could exacerbate the water runoff.
Plenty of moisture is available to this system. Interesting to note that the Precipitable Water value, which is the depth that would be achieved if all the moisture in a column of the atmosphere would precipitate as rain, is running 250% higher than normal for this time year. It would appear that we could see anywhere from 3/4 to 1 inch or more of rain from this system thru Tuesday.

With the temperatures warming, we should be able to make a big dent in melting the remaining snow on the ground. Frosty may be spending his final moments on the face of the earth. Those of you who are completely sick of seeing the once white, now brown stuff lying around, there is a way to expidite the melting process. Gentlemen! Start…your…..humidifiers!!!..
All things being equal, snow melts faster when there is more humidity in the air. When the air is dry, moisture from the melting snow will evaporate which in turn cools the surface of the snow slowing the whole melting process. On the flip side, more humidity means the air can’t evaporate as quickly. The surface can’t cool as much, allowing the snow to melt at a faster rate.

Just a quick update on overcast and fog situation for the remainder of the night. The cloud erosion that up to now had been occuring from east to west has stalled over the past couple of hours just to the east of Grand Island and Hastings. Difficult to say how the fog situation will transpire. It appears that lower visibilities will occur along the periphery of the cloud mass.
Look for cloudy conditions to start the day on Tuesday which should scatter out by the afternoon.

A mostly uneventful night tonight. Most of the area was under a blanket of clouds with a few isolated flurries mainly over southwest Nebraska. Most of the activity associated with an upper level wave was in southern Kansas
We are looking at a little relief from the recent cold, which we got a taste of today with temps cracking the 30 degree mark. Upper 30s will take us into the weekend with some low 40s next week. In between however is another storm system that will track into the Southern Plains. It might be just far enough north to catch us with a snow shower Sunday. More on the that Friday

Olympic coverage winding up and we are about to go on the air. Snowing in the Sandhills with some areas seeing heavy snowfall rates. Visibilities around North Platte have at times dropped to 1/2 miles and the Interstate is covered.
So far, its quiet in the Tri-Cities. To our southeast including Superior, Fairbury and Hebron, there is enough warm air aloft to promote a little sleet or freezing rain or a mix with snow. As of 11:30 returns were reaching the ground in Kansas and will be lifting into Nebraska in the next hour.
For the rest of the night, still expecting snow to develop and carry over to the morning commute. We could see amounts in the 2-3 inch range, with a little less south of highway 36 in Kansas. Fortunately winds will not be a problem.

Here’s a quick update as our winter storm crosses the state. The Tri-Cites remain on the southern fringe of a wider area of precipitation, but the snow keeps regenerating to our south and gets caught in the nortward flow. The result is periodic snowfall continuing through the evening and into Friday morning. Most of it will be light but there will be pockets of more moderate snowfall. One such line is setting up just west of Hastings at this writing (9:00 pm) and will be tracking through by 9:30. (more…)

Light rain showers have materialized between Hastings and Minden, lifting northeastward. Temperatures still remain above freezing so slicken roads are not a factor at this writing. Widespread rain and snow has pushed into southern Kansas to the south of Interstate 70 with scattered rain in north central parts.
Early tomorrow morning we could see brief periods of sleet or a rain/ snow mix before a rapid converstion to snow. Winter Weather Advisories will be effective until Friday morning as periods of snow will continue during the day into the evening hours before tapering off and becoming more scattered. Snowfall amounts still seem to be on track through Thursday night in the 3-5 inch rainge.

Tonight might be a night to howl at the moon. It would be fitting, because tonight is call the Wolf Moon, also known as the old moon or moon after yule. Tonight’s moon may seem bigger tonight and the reason is that in its elliptical orbit around the earth it is at it’s nearest distance. The end result is a moon that appears 14% wider and 30% brighter.

Our January thaw was a nice respite from what had become a rather rough winter. Last week the jet stream winds were tracking through California, pounding that state with a series of four powerful storms. Here in huskerland we were languishing in 40 degree weather, dodging potholes.
It’s apparently time to pay the piper. The jet stream is buckling southward as cold air from the polar region once again descends on the lower 48 sending us back into a December-like weather pattern. Fear not, it will not be THAT cold nor a prolonged cold snap. But for the rest of the week high temperatures will be in the low to upper 20s, and back to the single digit lows (sigh). Hang tough, the weekend will be better.

Wild western storm is heading toward the Rockies. I think the impact for us here in Nebraska will be minimal. Some rain is being realized over eastern parts of the state in addition to the Sandhills. Still a chance we could see some rain tonight but the lions share will stay to the north of Grand Island.
Keep your fingers crossed. Expecting the clouds to clear some as storm system pulls in some drier air by Saturday afternoon so a little sun is in the works. By late Saturday night, however the clouds will fill back in as colder air arrives with a little snow flying on Sunday. Not a great deal as far as accumulations, perhaps an inch along and north of Interstate 80.
