Big John: St. Patrick's Day Parade forecast looks perfect


Spring has sprung (though officially not until Friday evening at 6:45pm for the vernal equinox). I don't care; spring is here in my book and just in time to celebrate Saint Patrick's Day! And spring showers will follow later in the week. Thankfully no spring storms yet…

A quick word of thanks for joining us over the past weekend: running, walking and joking at GET YOUR REAR IN GEAR Saturday morning in clouds and mist; celebrating at the Hilton Head Wine + Food Festival at Sea Pines and it was wonderful when the sun came busting out; and parading and celebrating spring with the Hilton Head Saint Patrick's Day parade on Pope Avenue.

Thank you. And we look forward to the BIG FUN tomorrow! Weather will be perfect!

High pressure in charge today will slide offshore tonight. This is actually a “sub-tropical ridge” of high pressure, our first really warm one this season. Tranquil weather will continue with light winds and warmer temperatures through the night. Tomorrow a stronger shortwave will drop southeasterly from the Ohio Valley dragging a backdoor cold front late day.

What does that mean for the Parade? It means a warm, dry, mainly sunny day with more clouds developing in the afternoon. We'll start at 54 and we'll jump to 81 with a west breeze by mid-day. Use sunscreen and prepare for “warmer” weather. I will encourage you to “hydrate” but that's wasted on this day, I know. Just be safe and remember your neighbors and our visitors.

Now after Saint Patrick's Day (and there is a Wednesday coming up gang), that backdoor cold front will pass late day Tuesday night and get stuck again just south of us. Coastal trough develops Wednesday advecting moist air into the region, and new waves of energy follow that old boundary over us to end the week. That means shower chances for the rest of the week.

So the holiday festival will be fabulous for our visitors and for our merchants, the timing on the weather suits the most people and I will be safe for another year in forecasting. I will be your host with our dear friend Father Jeremiah McCarthy for the 8am Mass tomorrow morning at the Cathedral of St John the Baptist.

Sonny Dixon and Jimmy Ray will be your hosts, Dawn Baker and I will be your street reporters for the 191st Saint Patrick's Day Parade in Savannah. It's all on TV if you want to avoid the crowds on WTOC, Channel 11, Savannah (that's cable channel 6 for most areas). And you can watch anywhere in the world for FREE online at It'll be a “grand day”!
