Temps Are Set To Spike

The cold air is still in the region, but has a short life to live. The warmer stuff is building up and is ready to invade.

The really warm temps are still in my forecast and look to really get on the move later this week. The big issue that I have is just getting to that point! It's hard to beat the cold... it will happen... just takes a little while.

Wednesday will be pretty pleasant. Highs will hang anywhere between 40 & 50 degrees. Out in southern Kentucky towards places like Willimasburg, Somerset, London, and Corbin will be closer to the 50 degree mark. I actually wouldn't be surprised if one of those locations recorded highs in the low 50s. Other spots Hazard, Hyden, Pikeville, Paintsville, Prestonsburg, Salyersville, and Whitesburg will dwell in the 40-45 range. All of this is basically a step in the right direction.

The rest of the week will also include the much warmer temperatures. Thursday & Friday should both hit the 50 degree mark and pass it up with no problem.

The next chance of rain looks to arrive on Thursday or Friday. I am leaning maybe late on Thursday with an isolated shower, but Friday will be the day with the best coverage of showers of the two.

As you may have read here before... we use weather graphics housed by Weather Services International (WSI) I have talked about system upgrades before and again I find myself talking about the latest one. It was finally installed on Tuesday and it has a few more bells and whistles that I am very happy about. There are new things about it that will enhance our severe weather coverage and tropical weather forecast. I can now fly along with the Hurricane Hunters as they move through the sky. I will be able to see data on the screen as it becomes available. Numerous other little bug fixes and other tools that you folks at home will never notice, but I will be able to serve you with a little more ease!


The most powerful tool ever created for telling severe and disruptive weather stories.

When severe weather strikes, there isn't a moment to lose… for your audience or your weather team. TruVu Titan is the interactive storytelling tool that produces high-resolution pictures of dangerous and disruptive breaking weather without rendering. So you get the news out fast and keep your talent in the picture.

Photorealistic mapping and beautiful 3D Earth images make even fast-changing stories easy to understand with TruVu Titan. Audiences find Titan's vivid images more credible and compelling than the awkward, chunky graphics of other systems. We know, because we've tested Titan's graphics with real viewers. It’s a difference you can see on HD or standard definition broadcasts.

This year, TruVu Titan includes features that take tropical storm coverage to a new level. Hurricane Hunter provides the clearest, most accurate depiction of the path -- and probable future course -- of these deadly storms. Hurricane Tracker animates live, in real time, combining a constantly updated stream of incoming data from the National Hurricane Center so your talent stays on the air and on the story as it unfolds.

Hurricane Hunter follows the path of the hurricane-monitoring aircraft of the National Weather Service as they fly into the eye of these storms to gather data. The data from the aircraft updates automatically even while you are on-air, giving your coverage the immediacy and excitement of the front lines. And the new feature Spaghetti Tracks conveys the uncertainty of the rapidly changing situation as the jumble of multiple hurricane forecast models untangles as impact nears.

TruVu Titan includes these features for better storytelling and makes Titan easier to use than ever before.

Titan Impact is designed to provide on-camera meteorologists the tools they need to keep their viewers informed and safe from all of the dangerous phenomenon associated with severe weather outbreaks. Titan Impact provides critical intensity information on the top five hazards related to thunderstorms while other index products on the market only identify a single storm threat, such as tornadoes. This leaves meteorologists underserved in their mission and viewers dangerously under informed.

WSI Fire Weather Index is brand new and vital to communities that face this annual threat to life and property. This promotable, must-watch index is derived from our exclusive 4km RPM forecast model and is available as part of WSI's Vortex HD service. The WSI Fire Weather Index provides an easy to understand threat level for the potential of brush and wild fires based on a sophisticated algorithm incorporating wind, humidity and other atmospheric conditions along with surface conditions such as soil moisture.

With the acquisition of EEC, WSI is the premier radar company in the world.

Now TruVu Titan integrates with a greater variety of radar feeds than any other weather company. Here are some of the radar feeds now supported and radar features newly available in 2008:

EEC HiDef Radar - TruVu Titan displays live, sweeping high-definition EEC data, supporting up to 3840 bins -- a resolution as much as sixteen times greater than what you're experiencing now

EEC "Defender" Dual Polarity Radar – Titan also displays EEC's exclusive, dual polarity radar that allows you to detect, analyze, depict and warn viewers of more kinds of dangerous weather than any radar system in history. Now rain, sleet, snow and hail can be televised more clearly and accurately than ever before. Traditional radar cannot distinguish the difference between these types of precipitation.

Super Resolution NEXRAD Level II Data - In the spring and summer of 2008, the National Weather Service will upgrade its radar data to Super Resolution. Super Resolution data will improve the resolution of reflectivity data by 400% by reducing bin size from 1km to 250m. Best of all, the data is available to all Vortex Severe customers and Titan is ready to display that data now.

Also, there is a change in the way we categorize severe weather. This was released by the NWS in Jackson on Tuesday.

Beginning at 12 AM EDT, April 1, the hail size criterion for severe thunderstorm warnings in counties served by the Paducah, Louisville and Jackson, Kentucky National Weather Service Offices will change from three-quarter inch diameter to one inch diameter.
Beginning April 1 the National Weather Service Forecast Office in Jackson Kentucky will issue severe thunderstorm warnings for storms expected to produce hail one inch in diameter or larger, and/or damaging winds of 58 mph or greater. Special Weather Statements will be issued for storms producing hail from around one-half inch in diameter to less than one inch in diameter.
Local Storm Reports will continue to be issued for hail of three-quarter of an inch in diameter or larger.
The National Weather Service Central Region has conducted a demonstration in the state of Kansas and adjoining County Warning Areas over the past 4 years, utilizing a hail size criterion for issuance of Severe Thunderstorm Warnings of one inch in diameter, rather than the historical three quarter inch threshold.
This experiment was based on feedback from local partners, as well as scientific research conducted by Texas Tech University which demonstrated that significant property damage does not occur until hailstone sizes reach 1 inch in diameter. Central Region, along with the NWS Office of Climate, Weather and Water Services, is now taking steps to expand the demonstration area to encompass all Central Region weather offices.
In the Kansas demonstration area customers have indicated high satisfaction with the adoption of the 1 inch hail criterion. Media partners said warnings are more meaningful because the public knows there is a genuine risk of damage when a Severe Thunderstorm Warning is issued. Emergency managers agree warnings carry more weight and credibility.

One more thing... It was finalized Tuesday afternoon and I am happy to say that on Monday March 9th at 7pm I will be hosting a LIVE Issues & Answers The Mountain Edition. I will be joined by NWS Jackson Meteorologist-In-Charge Shawn Harley. We will be answering your questions LIVE and we'll also talk about severe weather preparedness month. If you have questions you can simply email them to me at jim.caldwell@wymtnews.com or just post them in a comment right here!
