Near the Leeward Islands and Greater Antilles: An area of disturbed weather over the central tropical Atlantic Ocean is expected to interact with an approaching tropical wave during the next couple of days. Environmental conditions are forecast to become conducive for some development thereafter, and a tropical depression could form mid to late week while the system is near or over the northern Leeward Islands, Greater Antilles, or southwestern Atlantic Ocean. * Formation chance through 48 hours, low, near 0 percent. * Formation chance through 7 days, medium, 40 percent.

A tropical wave is along 94W, from 20N southward, moving westward 10 knots to 15 knots. This tropical wave is moving through the SW corner of the Gulf of Mexico. Precipitation: no significant deep convective precipitation is related directly to this tropical wave.

A stationary front passes through 31N74W in the Atlantic Ocean, to 30N80W, continuing toward the west and the northwest, beyond the northeastern parts of Florida, and beyond Alabama. A surface trough is along 31N73W, to the coast of Florida near 28N, to 31N88W in SW Alabama. Precipitation: isolated moderate to locally strong is from 25N northward between 80W and 90W.

Upper level cyclonic wind flow, and isolated moderate to locally strong convective precipitation, are about 240 nm off the coast of the NW Yucatan Peninsula. Similar precipitation is in the NW corner of the area, with an inland Texas upper level trough. A few areas of widely scattered to scattered moderate and isolated strong convective precipitation are from 17N to 25N between 95W and 100W in the coastal plains and in the coastal waters of Mexico.

A ridge will remain in place from the eastern U.S. Across the eastern Gulf waters through Thu allowing for gentle to moderate winds and slight to moderate seas. Fresh winds are expected near and to the NW of the Yucatan Peninsula at night during the forecast period due to local effects.

The monsoon trough is along 09N/10N from 74W in Colombia, to central Costa Rica, and northwestward beyond 11N88W in the Pacific Ocean. Precipitation: scattered to numerous strong is from 11N to 15N between 80W and 85W, mostly in Nicaragua and in its coastal waters.

Upper level cyclonic wind flow, and isolated moderate to locally strong convective precipitation, are elsewhere from 63W westward; and in the Atlantic Ocean from 22N southward between 62W and Hispaniola.

Mostly fresh to some strong cyclonic wind flow is from Honduras northward from 82W westward. Fresh to strong NE to E winds, and moderate to rough seas, are from 18N southward between 70W and 81W. Fresh to moderate NE to E winds are from 70W eastward, and from 80W westward in the SW corner of the area. Moderate or slower winds are in the Windward Passage. Moderate seas are in much of the remainder of the Caribbean Sea. An exception is for slight seas in the SW corner.

The 24-hour rainfall totals in inches, for the period that ended at 28/1200 UTC, are: 0.46 in San Juan in Puerto Rico; and 0.40 in Tegucigalpa in Honduras. This information is from the Pan American Temperature and Precipitation Tables/MIATPTPAN.

The Atlantic ridge extends from the central Atlantic SW to the central Bahamas and is building over the eastern and central Caribbean. This pattern is supporting fresh to strong trade winds and rough seas across the central Caribbean that will persist into the middle of the week. Expect moderate to fresh E to SE winds and building seas over the northwest Caribbean today, with locally strong winds and rough seas across the Gulf of Honduras tonight. Looking ahead, winds and seas may increase northeast of the Leeward Islands Tue night into Wed ahead of an approaching tropical wave.

A stationary front passes through 31N74W, to 30N80W, continuing toward the west and the northwest, beyond the northeastern parts of Florida, and beyond Alabama. A surface trough is along 31N73W, to the coast of Florida near 28N, to 31N88W in SW Alabama. Precipitation: scattered moderate to widely scattered strong is from 27N northward from 66W westward. Fresh to strong SW winds are from 28N northward between 68W and 75W.

Slight seas are to the north of the line 31N13W 29N25W 25N47W 20N70W. Moderate seas are in the remainder of the Atlantic Ocean. Rough seas are from the Equator southward from 30W eastward. Moderate to fresh NE winds are within 150 nm on the NE end of the line to 360 nm on the SE end of the line, on either side of 27N19W 26N27W 25N33W 25N41W 17N50W 16N56W. Moderate to fresh southerly winds are from the monsoon trough southward between 10W and 33W. Mostly fresh to some strong SE winds are from 06N southward between 35W and 46W. Moderate or slower winds are in the remainder of the Atlantic Ocean.

A stationary front off northeast Florida along 30N will drift SE and gradually dissipate through Mon. The Bermuda- Azores high pressure ridge will build across the region thereafter into mid- week, supporting gentle to moderate winds north of 22N, and moderate to fresh winds south of 22N. Looking ahead, winds and seas associated with a vigorous tropical wave may increase northeast of the Leeward Islands Tue night into Wed, then move to the north of Puerto Rico and Hispaniola through Thu.

Into early August the weather will typically be dominated by a northwest-southeast split. Northwestern areas will probably experience rather breezy conditions with cloud and some outbreaks of rain or drizzle as weakening Atlantic frontal systems push eastwards across the UK. Toward the south and east it will tend to be drier and brighter much of the time, although there is also the small possibility of some thundery showers spreading in from the nearby continent. There are signs that a more widely settled period becomes more probable towards mid-August. Temperatures during this period will probably be close to or slightly above average overall, with the likelihood of some very warm conditions developing in the south and perhaps parts of the east at times.

No single weather type is expected to dominate through this fortnight. Spells of dry, settled weather slightly more likely, although these will alternate with wetter, cloudier conditions at times. The wettest conditions will probably be in the northwest, with the southeast tending to be driest. Through the period as a whole, warmer than average conditions are more probable away from the northwest, perhaps with some hotter spells to the southeast.

Tomorrow, Monday will be dry with sunny spells early on, but cloud will gradually increase from the west as the day progresses. It will be another warm day, with highest temperatures reaching 20 to 22 degrees in light or moderate south to southwesterly winds.

Monday Night: Rather cloudy with some patchy rain across northwestern areas. Staying dry further east with light southwest breezes. Lowest temperatures of 11 to 14 degrees.

Tuesday: Most places will be dry with some sunny spells, however there will be some patchy rain in the northwest and towards the south coast. Highest temperatures generally of 20 to 23 degrees in light winds, but a little cooler in the northwest.

Tuesday Night: Becoming mostly dry with clear spells. Winds remaining light with lowest temperatures of 11 to 15 degrees.

Wednesday: Mostly dry with a mix of cloud and sunny spells. A few showers will develop during the afternoon. Highs of 20 to 23 degrees with light winds.

Wednesday Night: A mix of cloudy periods and clear spells overnight with winds staying rather light. Generally dry too with lowest temperatures of 12 to 15 degrees.

Thursday: Mostly dry at first with a mix of cloud and sunny spells. Sunshine and scattered showers for the afternoon and evening. Humid with highs of 20 to 23 degrees and light winds.

Further outlook: Spells of rain are forecast for Thursday night and Friday, followed by slightly cooler and showery conditions.

Humidity, which in many ways impacts how we all feel this time of the year more than the temperature will be kept in check today and tomorrow, but increase to high levels on Tuesday and Wednesday before falling back somewhat by the end of the week.

July is, on average, our most humid month, so you can expect quite a number of days where you really notice the moisture in the air. The chart below gives us a lot of information about the upcoming weather tomorrow and Tuesday. The green line in the top box is the dew point. Notice how the dew point jumps during the morning Tuesday into the mid to upper 60s. This is a sign of a warm front coming through ushering the increasingly moist air.
