DISCUSSION
(TODAY THROUGH NEXT FRIDAY)
ISSUED AT 306 AM EDT SAT APR 29 2023
– OCCASIONAL SHOWERS THROUGH TUESDAY –
SUBSIDENCE AHEAD OF REINFORCED SHORTWAVE ENERGY WILL SUPPORT A
MOSTLY DRY MORNING TO START OUR DAY. SUBTLE SOUTHERLY FLOW AHEAD
OF AN ADVANCING COLD FRONT AND AFTERNOON EROSION OF THE LOW-LEVEL
STRATUS DECK THROUGH MIXING WILL BOOST AFTERNOON TEMPS TO NEAR 60
THIS AFTERNOON. THE COLD FRONT WILL THEN ARRIVE DURING THE
AFTERNOON AND EVENING AS THE REINFORCED MID-LEVEL SHORTWAVE DIVES
SOUTHWARDS ALONG THE BACKSIDE OF THE BROAD UPPER LOW. IT’S
POSSIBLE THERE MAY BE SOME AVAILABILITY INSTABILITY TO SUPPORT A
FEW RUMBLES OF THUNDER, BUT THE BETTER CHANCES FOR THUNDER WILL BE
FURTHER EAST WHERE AFTERNOON HEATING WILL BE BETTER ESTABLISHED
AHEAD OF THE FRONT.
THE UPPER LOW WILL DEEPEN FURTHER AS IT BECOMES CUTOFF AND SPINS
OVER THE REGION SUNDAY THROUGH TUESDAY. THIS WILL LEAD TO A GENERAL
FORECAST OF RELATIVELY COOL TEMPS WITH HIGHS IN THE 40S AND 50S AND
OCCASIONAL SHOWERS. MONDAY LOOKS TO BE THE COLDEST DAY THIS WEEK AS A
TIGHT WEST-NORTHWEST PRESSURE GRADIENT DEVELOPS AND SUPPORTS
ENHANCED COLD WITH OCCASIONAL SHOWERS. 850MB TEMPS DROP TO NEAR -3
TO -5C, SO EVEN SOME WET SNOW MAY MIX IN WITH RAIN SHOWERS AT TIMES.
– BRIEF DRY WEATHER WEDNESDAY WITH WARMING TEMPS TO END THE WEEK –
THE SURFACE LOW WILL FINALLY PASS EAST OF NEW ENGLAND BY WEDNESDAY.
A WARMING TREND CAN BE NOTED STARTING WEDNESDAY INTO THE END OF THE
WEEK WITH TEMPS GRADUALLY HITTING CLOSER TO MAY NORMS BY THURSDAY
AND FRIDAY.
– LOW CHANCE FOR RAIN THURSDAY AND FRIDAY –
LOW CHANCES FOR RAIN EXISTS THURSDAY AND FRIDAY AS A SHORTWAVE RIDES
DOWN THE LAST REMNANTS OF THE BROAD MID-LEVEL TROUGHING THAT WILL
LINGER OVER THE GREAT LAKES THROUGH THE END OF THE WEEK. GIVEN THE
POOR PROXIMITY TO THE SUPPORTIVE DYNAMICS ASSOCIATED WITH THE MAIN
SURFACE LOW TO OUR EAST, THESE SHOWERS SHOULD STAY LIGHT.

I just mowed my lawn for the 1st time this year! This is right about the normal time for the first mow every year! What a cold Spring! Get ready for wind chills in the 20’s, Incredible cold is coming!
Already low 60’s out with the sun! Just mowed my lawn for the second time already this early in the spring! That is usually unheard of with me this early! Now I’m gathering up my clubs for another perfect early spring day of golf! Who knew with all the nonstop repetitive COLD propaganda on here?!?!!?
Just mowed mine for the third time. Thick and so green. It’s growing like crazy. Love this time of year.
Yep, my lawn is beautiful right now Mark!

Quite a nice morning out there. Hope everyone gets to enjoy it before the cooler air moves in. Monday will have feels-like temps stuck in the 20s most of the day (May 1st).
The good news is the temps should moderate later in the week. Next weekend might be pleasant if the forecast doesn’t change.
There was a signal of a pattern change several days ago and it still seems to be on track. As a matter of fact it’s possible we could be heading for a slightly above average but that remains to be seen. I welcome it with open arms I’m ready for spring/summer.
With it being pretty much May now 4 months togo and it will be September already I love cold Springs keep on with the heat waves away yeahh!! And on that thought have a nice cool Saturday…INDY
No hot air is in sight! I love it!
Possible snowmobile trip to the UP in May! Incredible!
