Big changes are on the way for parts of Mexico and Central America this week.
Following a stretch of dry weather and record heat, a cold front will push across the Gulf of Mexico causing rain and thunderstorms to soak southeast Mexico, Guatemala, Belize and Honduras.
Much of April saw scorching heat from Villahermosa to Merida while rainfall was extremely scarce.
While April is typically warm and dry across this region, no rainfall was reported in both cities while temperatures soared well above normal.
In Villahermosa, there have been nine days with temperatures at or over 37.8 C (100 F) this month. The normal high is around 34 C (93 F).
Even more extreme is that 21 of the first 26 days of April had a temperature of 37.8 C (100 F) or higher in Merida, with a sizzling high of 110 degrees on the 25th and 26th.
This unrelenting heat will finally come to an end during the middle of the week as a cold front brings cooler air and widespread rainfall to the region.
The high temperature in Merida on Tuesday is expected to reach 41.7 C (107 F) prior to the arrival of this cooler air. By Wednesday, rain and thunderstorms will result to a high temperature of 29 C (84 F). A similar drop in temperatures is expected across the entire region.
While cooler air will be one impact of this approaching cold front, the heavy rain and thunderstorms will cause an elevated risk for flooding.
The greatest threat for flooding will be across the Mexican states of Tabasco and Chiapas, while also extending across much of Guatemala, Belize and western Honduras.
