AMENDMENT: TO 4/20/10 Post

NOTE: the rain conditions cited for Wednesday in the previous post are valid only through 8am. After that point rain chances will be close to zero. Everything else in the forecast post remains unchanged. In other words, for the majority of Wednesday there is close to no chance of rain after sunrise.

First Vestiges of Summer

The technical term for the cloud type that describes a thunderstorm is "cumulonimbus" in the most general way. There exists a variety of adjectives to this, but we'll leave it simple enough. I bring this up because the first vestiges of summer will be experienced the rest of the week ahead. But don't be surprised to see such a pattern be dismissed, as our not so official June 1/first day of summer is still far enough away that we could still see a significant stray from this pattern to occur i[ until mid-May.

SYNOPSIS: A short-wave trough will pass by to the north later this afternoon and evening. An appendant axis of lower pressure will exist with this system down the spine of the state. The result will be another day of inland shower and thunderstorm activity as was the case yesterday. Yet another one will pass on Wednesday. After these systems have passed strong high pressure will build north out of the Gulf of Mexico for the following several days which will exert its influence across the state through the rest of the week and into the weekend.

TODAY: A day very similar to yesterday will reign supreme with abundant sunshine for most of the day with no significant cloud coverage. Skies will be partly cloudy with a high along the immediate coast in the mid-70s but a good 5 degrees plus warmer once one gets west of US-1. I'm expecting that by late in the afternoon there could be a decent coverage of thunderstorm activity inland. I talked with someone from the Orlando area yesterday who stated that they experienced almost constant lightning in a storm they had there, if you can believe it.

Despite the fact that these storms will exist they will have an awful time trying to penetrate the modified oceanic air mass along the coast. Therefore, the coastal communities should be spared the wrath and only see an increase in clouds very late in the afternoon and into the evening with perhaps a driplet or two falling from the heavens upon our land (east of I-95).

All poetic license aside, expect that yesterday layed the blue print for today's weather. That is to say...photocopy the days.

WEDNESDAY: Actually, despite what I've been seeing/hearing over the media waves, I'm not so sure we will remain dry. Another short-wave trough (disturbance) will pass to the north but this one appears to be stronger.

With that said, the coastal communities might also be shared the wealth of the wet stuff on Wednesday with a thunderstorm or rain shower much more of a distinct possibility. Even so, if the coast does get in on the act one will still have to be in the right spot (or wrong spot depending on how one looks at it) to require the rain slicker.

In other words, there's a little better chance that the areas east of I-95 will see some rain and some of the boisterous loud bangers by late afternoon through the evening.

In fact, one of the models is indicating a healthy coverage up and down the east coast tomorrow by late afternoon lasting into the evening as it moves from west to east and out to sea.

But be not dismayed, because after Wednesday it will be a while before we see rain.

THURSDAY (and BEYOND): Despite what happens on Wednesday, if anything, we will start to see height rises in the 500mb layer which will result in a slow warming trend. Indeed, each day will be progressively warmer from Thursday through at least Sunday.

In fact, by Sunday the beaches could experience 85 degrees and areas west of I-95 will be looking at the big 9-0 on the old mercury (assuming one is not looking at a digital thermometer).

The next system to reach the state with any impact now appears to occur on Tuesday, but I wouldn't be surprised to see that get extended yet further out into the future if ever.

SUMMARY: Chance of rain on the coast Wednesday then warmer and dry into the weekend.
