Good Friday morning everyone!
Temperatures at the start of the day will be bottoming out right around 7am near the 40-degree mark in the city, though out in the country we may dabble in the upper 30s.
Here's a good link to current temperatures from every measuring station we've got.
Here's a list of fruits/vegetables and their sensitivities to frost/temperature.
Judging from the anticipated temperatures, we're not going to have a big issue here... Some of the greens at area golf courses may cause a delay in early tee-times, and any of those annuals that you perhaps put in the ground a little early may be stressed, but most plants that have come out on their own will be fine. It will only be about a 2-3 hour period that we'll see these sorts of near 40 temperatures, so it's not all that prolonged. If you're really worried about it, John Marra had a good tip today in his "Green Thumb Report": Simply tent some pieces of newspaper over the flowers. If the wind is up, you won't get the frost so you don't need the newspaper (so no worries about it blowing away if you do need it, because it would be calm).
Looking to the next few days, I'm going to drag out the phrase "TC Top Ten" :-) ... I think the way I use the label I've forced him in to 20-30 such days per year, but it's going to be great-- especially in the afternoons. Here's the weather maps for the next two days:
|HPC - Friday||HPC - Saturday|
As they say in the biz, "Big Bubble (of high pressure) ...No Trouble"
Temperatures will moderate from the get-go as well, because not only are we going to transition to southerly winds and warm air advection, you gotta remember that the Sun angle and length-of-day keeps getting higher and longer this time of year. Here's what the GFS is looking at for afternoon temperatures:
|GFS MaxTemps - Friday||GFS MaxTemps - Saturday||GFS MaxTemps - Sunday|
That 80-degree mark creeps close on Saturday :-) I think the 'official' numbers may be a touch shorter than these, but the bank thermometers, the car thermometers, and the feel on the skin will end up every bit of the mid 70s -to- low 80s. Now Sunday is a give-away for cooler weather, because (as we've been saying) the spotty showers start to lurk closer. It will be the start of an unsettled weather pattern that will hit-and-miss to start, but by early next week everyone will have a turn with the rain. Here's what it looks like on the weather maps:
|GFS - Sunday PM||GFS - Monday PM||GFS - Tuesday PM
We've got a Gulf-borne area of low pressure that's going to lumber around to our south early next week. General wind-flow in from the Gulf of Mexico will be very moist, and will eventually just keep on rising northward and push up against the Appalachian Mountains. Given the contrast of high pressure above it, the natural eventuality will be for the creation of an 'inverted trough'. If you recall, most low-pressure systems have trailing cold fronts that focus most of the action to the south if itself. This situation will be different, as a gradual percolation of moisture will focus some of the best rainfall to the north of its center. Here's a look at the overall rainfall expectations:
|HPC - Rainfall Accumulation - Sunday through Tuesday|
That's a lot of water hopping up the bunny trail-- a sharp cut-off too. This inverted trough will be something to keep an eye on in the coming days, as a change-of-focus closer to us will put flooding possibilities right back on the table.
