Yup ... but not to the extant that you see on TV/movies ... nowadays my storm chasing consists of me & a special app on my iPhone that lets me broadcast LIVE back to the studio & on the air. I have no problem with folks that do professional storm-chasing ... and as long as the amateurs are properly trained/educated than more power to them!
Meteorologist Keith Marler September 13, 2012 at 10:24 PM
Wow! ... some great work you're doing!! part of the limitation on current forecasting is the lack of accessible historical data - so thanks! As for weather station, each station relies on the various observations reported across a variety of networks: ASOS, NWS, MnDOT, etc - no one actually owns their private network. Again - great job & thanks!
Meteorologist Keith Marler September 13, 2012 at 11:41 PM
Ahhh ... no, I don't ... and I will DEFINITELY google up Dave's site tomorrow morning! Sounds VERY impressive!
Corey Butler Jr. September 13, 2012 at 11:47 PM
I just wanted to say thanks to you Keith for taking time to answer *all* the questions. We really appreciate it.
Meteorologist Keith Marler September 14, 2012 at 12:11 AM
No problem ... my pleasure!
Liana September 14, 2012 at 01:33 AM
Hello! My question is related to the one asked about dew point vs humidity. I am originally from NYC, and the forecasters there always talked about humidity and never dew point. Is there any reason why in one part of the country the forecasters speak in terms of humidity and in others they speak in terms of dew point? Thanks!

I just wanted to say that my morning wouldn't be complete if I didn't watch you and the rest of the Fox9 crew...you are as greatly needed as my cup of coffee!! You are all so much fun to watch!!! Keep up the good work!
Meteorologist Keith Marler September 14, 2012 at 02:13 AM
Nope ... not a regional thing ... it's just "traditional" to talk about relative humidity. It's not a bad thing, but it really doesn't help the viewer by itself ... Ian & I moved to dew point a few years ago and several others are slowly moving in that direction, too.
Meteorologist Keith Marler September 14, 2012 at 02:14 AM
Thanks, Bonnie!! Comments like yours help make getting up at 2am worthwhile! (ugh - that's just 5 hours away - time to hit the hay!)

Current data preferred

here's a link to a cool little site ... called the "e-wall" ... it's got a healthy mix of observation data & model data ... enjoy! http://www.meteo.psu.edu/~gadomski/ewall.html

Thinking of this past July and how hot it was, it didn't cool down at night. This past Tuesday when it was 95, when I woke up it was in the 60's. It seems like it doens't cool down at night during July. Is it because the dewpoint/humidity was a lot higher in July than it was this past week?
Meteorologist Keith Marler September 14, 2012 at 11:50 AM
Correct! The dew point is the limit (for the most part) to which we can cool the air at night - dew points in July on those hot & sweaty days are in the 60s or even the 70s (and rarely even in the 80s) ... dew points this week have mainly been in the 40s to around 50 (they're in the 30s THIS morning!), so we're able to get chilled in the AM!

I am very interested in weather, so I have a lot of questions....Sorry! It seemed like once August hit and a cold front went through, it seemed the weather completely changed. It got hot, but nothing like it was in July, and it didn't stay that hot either. Am I imagining it, or did something change? It seems like it happens every season. All of a sudden it gets hot and stays hot, or it gets cold and stay cold. I'm just wondering if this actually happens and what would cause it? Are cold and warm fronts actually that strong to do that?
Meteorologist Keith Marler September 14, 2012 at 12:13 PM
lol - you're not imagining anything! ... We did just that this year, as you observed. Warm & cold fronts can certainly be powerful, but think of them as the quickly shifting, transient weather makers - they CAN make a big impact, but they really need support in the upper layers in the atmosphere to raelly make a longer-term change. The biger shifts & "régime changes" (as I like to call them) occur when the large ridges & troughs (hills & valleys) in the Jet Stream (a fast-moving current of winds in the upper atmosphere) ripples around the US ... very simply put: when the Jet is to our north, we'll stay warmer (since it lets the warm air from the SOuth to surge our way) & as it shifts to our south we'll stay cooler (again, a gross simplification). So, yes - when the Upper-Air Pattern & its associated oscillations get stuck in a pattern, not much can change until the pattern shifts again!

mandie September 14, 2012 at 01:55 PM
I find your forcast to usually be spot on, but sometimes my co-worker has the complete opposite weather forcast that you gave. How is that possible? Aren't you all generally using the same models, for the most part?
Meteorologist Keith Marler September 14, 2012 at 02:58 PM
Thank you!
Meteorologist Keith Marler September 14, 2012 at 03:01 PM
Generally, yes. But: the subtle nuances of any forecast that can become more exaggerated have to do with the INTERPRETATION of the models. Think of any model data as simply "inspiration" ... the main thrust of a forecast is a balance of computer model data (a blend of several), eduacation, experience & good old-fashioned "gut feeling".
Terry Elliott September 14, 2012 at 03:20 PM
In mathematics, a "naive" forecast is one that ignores the science and uses a rule of thumb. An example in meteorology would be if I predict tomorrow's weather as being the same as today's weather. No science whatever. Here's the thing Keith: I bet I'd be WAY more accurate than most of the TV stuff I've seen, in the salient points people care about: temperature ranges and precipitation. You guys are super duper accurate about what happened today.. in the past. But "when will the rain start tomorrow?" and "when will it stop?"-- NOT SO GOOD. Terry
Susan September 14, 2012 at 03:28 PM
Hi Keith! My husband and I have always enjoyed watching you on Fox 9. Your quick wit and sense of humor resembles that of my husband, please give Susan my sympathy! I do have a weather related question. What is it that causes people with Arthritis to have more pain when the weather changes? Also, do you know of any good websites to find more information about this? Thanks for all you do!
Meteorologist Keith Marler September 14, 2012 at 03:30 PM
Not sure how to respond to that Terry, not knowing your background/etc - other than I'd take that bet & be VERY confident I'd win ;-)
Meteorologist Keith Marler September 14, 2012 at 03:35 PM
I'll pass along your thoughts to her, lol - perhaps there's a support group? Weather changes & the old "feel it in my bones" is theoretically a result of the changes in atmospheric pressure ... the bigger the storm system approaching, the bigger the change possible ... (but this correlation is still debated) here's a link for you: http://www.johnshopkinshealthalerts.com/reports/arthritis/44-1.html
Saxony Pohlman September 14, 2012 at 05:51 PM
Hey Keith! My question is kind of silly, but why is it that when we have REALLY hot weather we get thunderstorms? P.S. Love you on Fox 9!
Meteorologist Keith Marler September 14, 2012 at 09:28 PM
Not silly at all!! ... Hot & humid weather are the perfect "fuel" for thunderstorms and get the air really churning ... hence why thunderstorms are much more common in the warmer months - although we DO get thunder-snow every so often!
Meteorologist Keith Marler September 14, 2012 at 09:34 PM
Thanks to everyone for all of your questions! It was a pleasure to take part in this & I'd like to give the Maple Grove Patch & all of the community Patches a great big "Thank You!" for letting me be involved!
Meteorologist Keith Marler September 14, 2012 at 09:35 PM
