I actually went a bit cooler tomorrow, given the high busts the last 2 days (I forecasted 89 and 91....verified 88 and 88).

The NAM, GFS and EURO all have shra around 21z-0z, so I went Day 3: 87F / 75F / 10kts / .07"

The problem is, if it doesn't rain then it's a double whammy for me. Oh well, let's see what happens.

it's tough almost any way you slice it...

Monday I thought they'd be cooler with SHRA, got hit hard twice.

today for example, the high of 89F was at 10:41 a.m. :lightning:

Yeah Miami is proving to be harder than I thought it would. The winds have also over-performed both days, so I'm beginning to think I should've gone 12 kts tomorrow instead of 10.

Man! Sad I missed out on the contest this year... One thing I've noticed, just going back and looking at the past three days, is that those low temperatures are going to depend on WHEN they see the rain, if any. Yesterday, it rained earlier in the afternoon, allowing temperatures to get back into the middle 80s before slowly dropping into the upper 70s. Also, the WIND DIRECTION plays a huge part in forecasting the overnight low... If there's a bit of northerly wind overnight, temperatures will drop relatively fast. However, if you continue to see an easterly (or even a westerly wind to some extent) it won't dip much below 76/77. Also, the rain is a crap shoot as you can have some areas of Miami pick up 2 inches, but the official recording station only picks up .04 :axe:

You can't go wrong with a forecast of 90/77/12/.10 each day for Miami... that is until the front tries to work its way into South Florida which you also have to be careful about, but that's next week.

Good luck to everyone forecasting for Miami! It's a tricky spot to forecast for, as many of you are finding out now, but it's also enjoyable! BTW, I grew up on the west coast of Florida so I know what you are going through forecasting those stupid overnight lows :lol:

Again the Low screws me over.

Oh well. The 10z HRRR has CI around 17-18z, so let's see what that does for us.

Right now we're starting off warmer than the past 2 days' 12z obs, so if we don't get some convective debris this afternoon many people will bust low on their forecast highs.

Heh! I need to make sure to look at the radar down there this afternoon to see how well the HRRR does... I haven't looked at it much for Florida seabreeze showers so not sure how well it does... Should be fun to see :guitar:

Hmmmm... busted on low, no north winds. Should of kept with my original 77.

Anyway, this mornings sounding:

With a forecasted CAPE of 4500 j/kg to the stratosphere and a LI of -7, As with almost any day in S Florida, there is going to be some storms today. I expect 2 storm modes today.

1. Small topped showers that move slowly with the easterly flow that will be present all day (already some just off the coast this morning)

2. Afternoon/evening thunderstoms that will attempt to break the *slight* mid-level cap/ Dp depression and will slowly drift westward. These ones I suspect will only be able to get the kick-start mechanism they need by the either sea-breezes/outflow boundaries colliding.
