Winter Storm Watch in effect...

9:22 PM Sun, Feb 10, 2008 |

A Winter Storm Watch is in effect for much of North-Central Kentucky and all of Southern Indiana for late Monday through Tuesday morning. Less than a week removed from the latest round of spring-like severe weather here in Kentuckiana, the area is now bracing for the possibility of some severe winter weather...

The National Weather Service will issue a Winter Storm Watch when there is a potential for heavy snow or significant ice accumulations 24 to 36 hours in advance of an approaching storm system. That is exactly the possibility that we are looking at by Monday night.

A retreating area of Arctic high pressure will continue to feed very cold conditions into the area on Monday in advance of a developing area of low pressure approaching from the southwest. With cold air already in place, moisture will begin streaming into the area ahead of this low pressure system setting the stage for significant winter weather.

At this time, we are looking at precipitation starting in the form of snow for North-Central Kentucky by late afternoon or early evening. This band of snow will lift northward into Southern Indiana during the evening hours and could fall moderately heavy at times.

As some warmer air begins to work in aloft, a change from all snow to a wintery mix of snow, sleet and freezing rain should occur during the overnight hours Monday night for the metro area. Unfortunately, in addition to some heavy accumulations of snow, some significant icing may occur for parts of the area.

Expect the wintry mix to change over to a cold rain for Louisville sometime Tuesday morning as temperatures warm to above freezing, before precipitation ends during the afternoon. Current projections place Louisville in a band of 1 to 3 inches of snow and ice accumulations. That band extends from a line connecting E-town and Bardstown to the south, to a line connecting Paoli and Madison to the north. North of that, a band of 3 to 6 inches appears possible across Southern Indiana.

Eventual snow and ice totals will be highly dependent on the exact track of this winter storm system. A track further to the north will mean lesser totals for the area. A track further to the south will mean higher totals. Stay tuned for future updates.

Yeah, It is true to what Shawna is saying. What I do is just go completly oppisite of what the station is saying. They are not accurate at all. They are never right. I think their radars are set in another state!

Thank you for your comments Shawna. First of all, forecasting snow amounts can be very tricky. Admittedly, the snow forecast for parts of Southern Indiana wasn't as good as we'd like it to be. Computer weather models were projecting the axis of heaviest snow to be further north than what it panned out. However, snowfall forecasts for the metro area and for much of Kentucky turned out very good. Louisville officially picked up about 4.5 inches of snow while we were forecasting 4 to 6.

Now about the Tornado Warning that was issued in the storms from Tuesday February 5th. It is a common misconception that TV meteorologists are responsible for issuance of advisories, watches and warnings. However, the truth is that advisories, watches and warnings are all issued by the Natiional Weather Service. Our Louisville NWS office issued that particular tornado warning for Washington County last week. When these warnings are issued, it is the Television station's primary duty to pass this "potentially" life threatening information to the public. So whenver, a warning is issued, especially a tornado warning, it is taken very seriously here at WHAS11. Sometimes, just like in a snow forecast, these warnings don't verify. But that is OK, we would much rather error on the side of caution when it comes to severe thunderstorms or potential tornadoes. Imagine the type of emails we would get if a tornado did occur and no warning was issued?

How come the outcomes of weather forcasted and the actual weather we get has been so off the past few weeks?
I live in Salem-Pekin area Indiana and this is twice now that we were forcasted significant snow accumulations and nothing panned out. Which is great.
Then last Tuesday you had Tornado Warning around midnight with 100 mph winds and I grab my son go running to the neighbors house and it wasnt doing anything but raining? I just feel something is off with the computer models or something because now the public just feels like you cant really on a forcast.
