July 2012 General Discussion


Tropical

Recommended Posts

Ya I wouldn't be suprised if that's the case. Where ever the high clouds are right now will probably be the same areas that see storms later. It's going to be a close call.

Actually you might be right. I was looking at either the 13z or 14z HRRR, and the 15z shifted it slightly north. Also, Milwaukee is on the northern edge of the high clouddeck, so I might just be overly pessimistic. A few tenths of an inch of rain would be welcome, although more would obviously be better.

from LOT

CONCERNS THEN SHIFT TOWARDS LATE TONIGHT INTO EARLY TUESDAY

MORNING. ANOTHER STRONGER AND MORE DEFINED MID LEVEL WAVE NOTED ON

LATEST WATER VAPOR IMAGERY ACROSS THE DAKOTAS WILL DROP SOUTHEAST

ACROSS THE REGION. THIS WAVE WILL ENCOUNTER A STRENGTHENING LOW

LEVEL JET ADVECTING A VERY MOIST AIR MASS INTO IT AND OVER A LOW

LEVEL BAROCLINIC ZONE DROPPING SOUTH THROUGH THE CWA...WITH

DEVELOPMENT EXPECTED ACROSS CENTRAL WISCONSIN. THIS WAVE/FORCING

AND STEERING FLOW WILL SHIFT THIS CLUSTER OF SHOWERS/THUNDERSTORMS

SOUTHEAST ACROSS NORTHERN ILLINOIS AND NORTHWEST INDIANA...WITH

THE BEST CHANCES EXPECTED NORTH OF LINE FROM DIXON IN ILLINOIS TO

FOWLWER IN INDIANA AND THE BEST CHANCES WITH REGARDS TO TIMING

EXPECTED TO BE AFTER MIDNIGHT. AS THIS COMPLEX MOVES ACROSS THE

AREA IT WILL ENCOUNTER A VERY MOIST AND UNSTABLE ATMOSPHERE WITH

HIGH DEWPOINT/PWAT AIR IN PLACE. CONCERNS DURING THIS TIME FRAME

WOULD BE FOR SOME ISOLATED LARGE HAIL...BUT WITH CONCERNS MORE

TOWARD THE HEAVY RAIN POTENTIAL. ALTHOUGH THIS DOES NOT APPEAR TO

BE A CLASSIC HEAVY RAIN SETUP...MANY FEATURES ARE IN PLACE TO

PROVIDE SEVERAL ROUNDS OF SHOWERS AND THUNDERSTORMS THAT WILL ALL

HAVE THE POTENTIAL TO PRODUCE HEAVY DOWNPOURS...INCLUDING LOW

LEVEL FLOW BRIEFLY ORIENTING ITSELF WITH REGARD TO THE BAROCLINIC

ZONE SUCH TO BRING AT LEAST SOME PERIOD OF POTENTIAL TRAINING OF

CELLS. WILL CONTINUE TO MAKE MENTION OF THESE THREATS IN THE HWO

AS WELL AS AN ESF.

if we don't score tonight and tomorrow it could be a very disappointing week. I'm not sold we're in

a good spot later in the week and im afraid we'll be stuck with most of the precip missing n/s

good call

COMPLEX AND LOW CONFIDENCE FORECAST FOR THIS TAF CYCLE. GUIDANCE

HAS BEEN VERY MUCH OVERDONE ON SHRA AND TSRA THIS EVENING WITH

CURRENT MIDLEVEL WAVE SLIDING OVERHEAD. RELYING ON RADAR AND IR

SATELLITE TRENDS AND THE LACK OF LIGHTNING WITH ACTIVITY IN THE

REGION THERE IS NO GOOD REASON TO BELIEVE THE TRACON AREA WILL SEE

TSRA THIS EVENING. EVEN THE SHRA OVER WISCONSIN HAVE STRUGGLED

AGAINST THE CAPPED ATMOSPHERE DESPITE MESOANALYSIS SHOWING PLENTY

OF ELEVATED INSTABILITY. SO INTO THE OVERNIGHT HAVE GONE WITH A

VCSH MENTION IN THE TAFS...THOUGH THERE MAY BE A COUPLE

SHOWERS/SPRINKLES MOVING OVER THE TERMINALS FROM TIME TO TIME.

LATER OVERNIGHT INTO EARLY TUESDAY MORNING...A FRONTAL BOUNDARY

DRAPED ACROSS CENTRAL AND NORTHERN WISCONSIN WILL SAG SOUTH OVER

THE TERMINALS...AND ANOTHER MIDLEVEL SYSTEM MAY COMBINE TO RESULT

IN A BETTER CHANCE FOR PREVAILING SHRA/POSSIBLY TSRA. DO NOT HAVE

VERY HIGH CONFIDENCE...BUT INCLUDED VCTS WITH PREVAILING -SHRA FOR

THIS TIME PERIOD. IF ANY GOOD SHOWER ACTIVITY DOES GET

GOING...COULD SEE SOME LOWERING OF CEILINGS...BUT NOT EXPECTING A

DIP BELOW VFR. THERE MAY BE OPPORTUNITIES FOR MORE SHRA/TSRA TO

DEVELOP DURING THE DAY TUESDAY INTO TUESDAY NIGHT AS MORE MIDLEVEL

FEATURES DROP SOUTHEAST AND THE FRONT STALLS NEAR THE AREA.

HOWEVER...NOT NEARLY ENOUGH CONFIDENCE TO INCLUDE MENTION IN THIS

SET OF TAFS.

starting to see some increase in returns over MN...wonder if we'll see things start to build downstream

That's the look of it. Interestingly the HRRR has way less thunderstorm activity than what's actually going on, hopefully a trend: http://rapidrefresh.... Jul 2012 - 23Z

Looks like Madison is in the line of fire for at least a decent stratiform rain event, probably going to be tons of boomers and spider lightning in that. HRRR keeps the actual squall to the south, but that can easily change.

Shower moving through Madison on the downstream end of the system, a little wet out there. Low level temps an extremely warm 85/72 despite the rain... whoever gets hit with the main updrafts in this squall are gonna regret it if they own a car.

.UPDATE...850-700 MB FRONTOGENESIS VIA CONFLUENT FLOW BTWN UPPER

RIDGE TO THE SOUTH AND UPPER TROUGH OVER HUDSON BAY IS TRIGGERING

A WEST TO EAST BAND OF SHOWERS AND TSTORMS ACROSS SRN MN INTO

CENTRAL WI. THIS BAND OF FRONTOGENESIS WILL SHIFT SOUTH INTO SRN

WI AND NRN IL LATE TNT AND STALL INTO TUE AM. EXPECT ROUNDS OF

CONVECTION FROM MADISON TO MILWAUKEE AND SOUTH. CLOUD BASES WILL

BE VERY HIGH TO START AND WILL GRADUALLY LOWER INTO TUE AM. NEARLY A

The little cluster of storms that developed over the western portion of my county now have organized themselves into a nice little show for Logansport/Kokomo areas. Another little cell recently popped up in the extreme northern portion of Jasper County. Although these little boomers are missing me, I am still getting a nice light show. Can't complain there!

It has awaken everyone here. Some scattered power outages.

Thunderboomers near RFD should make it here later on this morning. At first I thought it might be a narrow miss to the east (where things have been developing the past few hours). However, it looks like it should make a beeline towards my area. Pretty excited as these boomers have played hard to get this summer :(

Sitting here at a wet 69° here. Looks like the forecast is going for 80° today only. Milwaukee can't catch a break! Brewers - looks like Racine got some good rain this morning! and Kenosha definitely did.

Kudos to the HRRR! :)

Todays the anniversary of the hottest afternoon Detroit has ever seen, with a high of 105F set July 24, 1934. We had hit 104 five other times (in 1918, also in 1934, twice in 1936, and in 1988)...but this time we actually hit 105. Interesting that the low was a relatively comfortable 69F, compared to so many of our other hot days.

I would love to see this record broken! Wonder what the dews were during the day. Must have been low given the swing in temp.

Yeah it did a good job.

Looks like a solid band of rain coming right towards Waukegan. Looks like I might be able to catch the northern edge.

Yeah I wish I knew the dews. Whats interesting is that when looking at past heat data, I noticed that some of the dews were seemingly atrocious in some our heatwaves in the 1930s/1940s, some of the days that may have not had the gaudy 100 numbers but with highs in the upper 90s and lows near 80. July 1921, which at the moment stands as our 3rd hottest July/month on record (behind July 2011 and 1955) had simply gross lows (in fact the avg low in July 1921 was warmer than either 1955 or 2011), despite the months hottest temp being a non-gawdy 96F. I cant imagine that kind of weather in those non-air conditioned days.

Our hottest day (mean temp 91F) was Aug 6, 1918 (104/78) and it appears it was grossly humid that day. Following the day, the morning low on Aug 7th was just 82F (it was in the mid-upper 80s most of the overnight) before once again surging to 100F. had not a cool front allowed temps to dip into the mid-70s during the very late evening, that low of 82F would be the warmest low on record (rather than the current 80F which has been set 4 times (7/1/1931, 7/5/1921, 7/18/1942, and 8/1/2006)
