Nicaragua and Costa Rica are braced for a bit of weather tonight. A slight cold front is due to first hit the north and central regions of Nicaragua, meteorologists from the country's Institute of Territorial Studies (INETER) said.

“We're expecting a drop in temperatures and strong winds, some light to moderate precipitation in the northern and central regions of the country, and maybe on the Pacific too,” meteorologist Mauricio Rosales told the newswire ACAN-EFE.

Costa Rican meteorologists told The Tico Times they also forecast cooler air, wind and light rain for this country late tonight and throughout Wednesday.

In Costa Rica's Central Valley, where San José lies, today's temperatures will range 14-28 degrees Celsius (about 57.2-82 degrees Fahrenheit); 21-35 C (69-95 F) in the northern Pacific; 20-34 C (68-93.2 F) in the central and southern Pacific and 21-30 C (69-86 F) in the north and south Caribbean.

Tomorrow, the front could come in fuller and dip these temps down by as many as 2 degrees Celsius, bringing stronger winds and rain with it, said National Meteorological Institute analyst Gabriela Chinchilla.

For the weekend a complete forecast was not yet ready, Chinchilla said, but by Thursday she reckons temperatures will rise back up again, winds will slow and make way for a clear, dry weekend in most parts of the country.
