Yesterday was humid, warm and cloudy in the morning, but the skies cleared up by midday, as the NAM had predicted.
This morning has been sunny, mild and still.
From the NWS in Melbourne, FL: High pressure will elongate through the area today, bringing with it stable weather. There will be some gentle breezes onshore near the coast, but otherwise, no major weather events are forecasted at this time.
The NWS in Melbourne, FL, forecasts (for Orlando, FL) a sunny day, with a high temperature of 78 F. The winds will be from the northeast at 5-10 mph. This evening will be mostly clear, with a low temperature of 61 F. The winds will be from the northeast at 5 mph, becoming calm by midnight.
The NWS in Melbourne, FL, has issued a Hazardous Weather Outlook concerning the possibility of riptides at the coast.
The visible satellite imagery shows very few clouds over the state today. This image has been excluded from today’s post.
The 12Z upper air sounding from Tampa Bay, FL, shows a humid surface layer, but surprisingly low humidity above 850 mb. There was 0.71 inches of precipitable water present in the column this morning. There was no Convective Available Potential Energy (CAPE), no Convective Inhibition (CIN), and the Lifted Condensation Level (LCL) was 128 m. There was a large thermal inversion near the surface and the 0-3 km lapse rate was 2.4 C/km. The hodograph shows that the low-level shear was 2 kts (due mostly to directional changes) and the deep-layer shear was 12 kts (due mostly to speed changes).
The surface observations chart (from the SPC Mesoscale Analysis Map) shows mild temperatures and high surface humidity. The skies are sunny(according to the sensors) and the winds are light and from the northeast.
The surface pressure chart (from the SPC Mesoscale Analysis Map) shows that high pressure has settled over the area, with no strong pressure gradients. The RAP shows that this trend will continue for at least the next six hours.
The NAM 250 mb chart shows moderate zonal to slightly northwesterly flow.
The NAM 850 mb chart shows no strong thermal advection. This chart has been excluded from today’s post.
The Nested NAM simulated reflectivity chart and 12-hr precipitation chart show the skies clearing in the next hour or two. These chart have been excluded from today’s post.
The Nested NAM predicts that the high temperatures will peak in the mid 70s F today.
The low temperature is predicted to be in the upper 50s F just before sunrise tomorrow.
The Nested NAM shows that the dewpoints will remain in the 50s F for most of the day.
The Nested NAM shows that strong gusts are unlikely today. This chart has been excluded from today’s post.
The Nested NAM predicts only a few clouds this evening. This chart has been excluded from today’s post.
Today looks to be pleasant. I hope to get outside for a little bit, but I’m way behind on a project, so I probably won’t get to go to the beach today after all.
Thank you for reading my post.
